Camila is organizing a bake sale at her school in Austin, Texas, to raise money for a local charity. She plans to sell cookies for $2 each and brownies for $3 each. If she estimates that she will sell about 15 cookies and 10 brownies, what is the best estimate of the total revenue she will make from the bake sale?
- $60 ✓
- $50
- $45
- $75
Why: To estimate the total revenue, first estimate the number of cookies and brownies sold. Camila plans to sell about 15 cookies at $2 each, which is approximately 15 × 2 = $30. For the brownies, she plans to sell about 10 at $3 each, giving an estimate of 10 × 3 = $30. Adding these amounts together, $30 + $30 = $60. Therefore, the best estimate of the total revenue is $60.
Valentina is selling fresh oranges at a market in McAllen, Texas. Each bag of oranges costs $6. If Valentina sells 8 bags in one day, how much money does she make from selling the oranges?
- $40
- $54
- $48 ✓
- $38
Why: To find out how much money Valentina makes, we multiply the number of bags sold by the price per bag. So, 8 bags × $6 per bag = $48. Therefore, the correct answer is $48.
Maria is planning a school field trip to the Gulf Coast in Texas. The bus can hold 45 students. If there are 32 students signed up now, how many more students can sign up before the bus is full?
- 10
- 12
- 13 ✓
- 14
Why: To find out how many more students can sign up, subtract the number of students currently signed up from the total capacity of the bus. The calculation is 45 - 32 = 13. Therefore, 13 more students can sign up before the bus is full.
Paola went to a local festival in El Paso and decided to buy some delicious breakfast tacos. Each taco costs about $3. If she wants to buy 7 tacos, which number is closest to the total amount she will spend?
- $21 ✓
- $27
- $24
- $30
Why: To find the total amount Paola will spend on 7 breakfast tacos, you multiply the cost of each taco ($3) by the number of tacos (7). So, 3 × 7 = 21. The closest estimate of her total spending is $21.
Kai and his family went to Fredericksburg, Texas, to pick peaches. They picked 48 peaches on Saturday and 36 peaches on Sunday. If they want to make peach preserves, how many peaches do they have in total? Estimate the total number of peaches.
- 80
- 90 ✓
- 100
- 110
Why: To estimate the total number of peaches, you can round each number. Round 48 to 50 and 36 to 40. Then, add the rounded numbers: 50 + 40 = 90. Therefore, the best estimate for the total number of peaches is 90.
Lucas is organizing a bake sale at his school in Austin to raise funds for a field trip. He plans to sell cupcakes, cookies, and brownies. He orders 45 cupcakes, 36 cookies, and 27 brownies. To estimate how many treats he has in total, what is the best estimate of the number of treats Lucas will have?
- 100
- 110
- 120 ✓
- 130
Why: To estimate the total number of treats, we can round each number to the nearest ten. Rounding 45 cupcakes to 50, 36 cookies to 40, and 27 brownies to 30 gives us 50 + 40 + 30 = 120. Therefore, the best estimate of the total treats Lucas will have is 120.
Hannah went to the Texas State Fair and bought 4 servings of funnel cakes. If each funnel cake costs about $5, what is the best estimate of how much Hannah spent on funnel cakes?
- $20 ✓
- $15
- $25
- $30
Why: To estimate the total cost, multiply the number of funnel cakes by the cost of each one. Here, Hannah bought 4 funnel cakes at $5 each. So, the estimate would be 4 * 5 = $20. Therefore, the best estimate of how much Hannah spent is $20.
Valentina is planning a picnic at Padre Island National Seashore. She wants to bring sandwiches for her 7 friends. If she makes approximately 30 sandwiches, about how many sandwiches will each friend get if she divides them equally?
- 4 ✓
- 5
- 3
- 6
Why: To find out how many sandwiches each friend will get, divide the total number of sandwiches (30) by the number of friends (7). Estimating, 30 divided by 7 is about 4. Therefore, each friend will get approximately 4 sandwiches.
