Cognitive demand: medium. Typical question shape: Rate of change in real context (e.g., $/hour, miles/gal).
Aisha is organizing a school fundraiser by selling boxes of cookies. Each box sells for $5. If she sells 12 boxes on the first day and 8 boxes on the second day, how much money does Aisha make in total from the two days of sales?
- $100 ✓
- $75
- $60
- $80
Why: To find the total amount Aisha makes, first calculate the total number of boxes sold: 12 + 8 = 20 boxes. Then, multiply the number of boxes by the price per box: 20 * 5 = $100. Therefore, Aisha makes $100 in total.
Lila is organizing a school fundraiser selling cookie boxes. Each box contains 12 cookies, and she is selling each box for $5. If Lila sells 18 boxes, how much money will she make from the fundraiser?
- 90 ✓
- 108
- 72
- 54
Why: To find out how much money Lila will make, multiply the number of boxes sold by the price per box. Lila sells 18 boxes at $5 each, so you calculate 18 * 5 = 90. Therefore, Lila will make $90 from the fundraiser.
Tatiana conducted a survey in her class to find out how many books her classmates read last month. The results are shown below: 5, 7, 6, 4, 8, and 5 books. What is the average number of books read by her classmates?
- 5
- 6 ✓
- 7
- 8
Why: To find the average number of books read, add all the books together: 5 + 7 + 6 + 4 + 8 + 5 = 35. There are 6 students, so divide the total by 6: 35 ÷ 6 = 5.833... which rounds to approximately 6. Therefore, the average number of books read is 6.
Sofia runs a small bakery and tracks the number of cupcakes sold over five days. The sales are as follows: Monday - 30 cupcakes, Tuesday - 35 cupcakes, Wednesday - 40 cupcakes, Thursday - 50 cupcakes, and Friday - 45 cupcakes. What is the average number of cupcakes Sofia sold per day over these five days?
- 40 ✓
- 45
- 35
- 50
Why: To find the average number of cupcakes sold per day, first add the total number of cupcakes sold over the five days: 30 + 35 + 40 + 50 + 45 = 200. Next, divide the total by the number of days: 200 ÷ 5 = 40. Therefore, the average number of cupcakes sold per day is 40.
Priya recorded the number of hours she studied for her Algebra exam over five days. The hours were: 4, 6, 5, 7, and 3. What is the average number of hours Priya studied each day, rounded to the nearest whole number?
- 5 ✓
- 6
- 4
- 7
Why: To find the average, first add the total hours studied: 4 + 6 + 5 + 7 + 3 = 25 hours. Then, divide by the number of days: 25 ÷ 5 = 5 hours. The average number of hours Priya studied each day is 5, which rounds to 5 when expressed as a whole number.
Carlos is tracking the number of books he reads each month for five months. The number of books he read each month is as follows: January: 6, February: 8, March: 9, April: 7, May: 5. What is the average number of books he read per month over these five months, rounded to the nearest whole number?
- 7 ✓
- 8
- 6
- 9
Why: To find the average number of books read, first add the total number of books: 6 + 8 + 9 + 7 + 5 = 35. Then, divide by the number of months: 35 / 5 = 7. Therefore, the average number of books Carlos read per month, rounded to the nearest whole number, is 7.
Mateo is organizing a local fundraiser to support the community park. He sells tickets for the event at $5 each. On the first day, he sells 12 tickets. If he continues to sell tickets at the same rate for 4 more days, how much money will he have earned from ticket sales at the end of the 5 days?
- $240
- $300 ✓
- $60
- $100
Why: To find the total amount earned, first calculate the total number of tickets sold. Mateo sells 12 tickets on the first day and continues to sell 12 tickets each day for 4 more days, which means he sells a total of 12 × 5 = 60 tickets. Then, multiply the total number of tickets by the price per ticket: 60 tickets × $5 = $300. Therefore, Mateo will have earned $300 from ticket sales.
Imani works at a local coffee shop where she earns $12.00 per hour. This week, she worked 4 hours each day from Monday to Friday. What is Imani's total earnings for the week?
- $240.00 ✓
- $48.00
- $60.00
- $180.00
Why: To find Imani's total earnings for the week, we first determine the total number of hours she worked. She worked 4 hours per day for 5 days, so the total hours is 4 * 5 = 20 hours. Next, we multiply her hourly wage of $12.00 by the total hours worked: 12 * 20 = $240.00. Therefore, her total earnings for the week is $240.00.
