1. 40 ✓
2. 30
3. 50

Why: To find the total number of feathers, multiply the number of birds by the number of feathers each bird has. There are 4 birds and each has 10 feathers, so you calculate 4 * 10 = 40 feathers in total.

1. 135 ✓
2. 90
3. 150
4. 180

Why: To find the total number of pecans, you multiply the number of trees by the amount of pecans each tree produces. So, 3 trees × 45 pecans/tree = 135 pecans in total. Therefore, the correct answer is 135.

Janelle is organizing a bake sale at her school in Austin, Texas. She baked 2 dozen cookies and 3 dozen brownies. How many individual treats does Janelle have in total?

1. 60 ✓
2. 48
3. 36
4. 24

Why: First, we need to calculate the total number of cookies and brownies. Janelle has 2 dozen cookies, which is 2 * 12 = 24 cookies. She also has 3 dozen brownies, which is 3 * 12 = 36 brownies. Now, we add the two amounts together: 24 + 36 = 60. Therefore, Janelle has 60 individual treats for her bake sale.

1. 80 ✓
2. 70
3. 75
4. 90

Why: To find the number of rows of cotton plants, divide the total number of plants by the number of plants in each row. So, 3,200 ÷ 40 = 80 rows. Therefore, the correct answer is 80.

Pablo is visiting the San Antonio Stock Show, where he sees that three farmers are selling different types of pecans. Farmer A has 250 pounds, Farmer B has 400 pounds, and Farmer C has 150 pounds. What is the total number of pounds of pecans that all three farmers have together?

1. 800 ✓
2. 500
3. 600
4. 700

Why: To find the total number of pounds of pecans, add the amounts from the three farmers: 250 + 400 + 150. This equals 800 pounds. Thus, the correct answer is 800.

3. 240
4. 180

Why: To find the total number of pencils, multiply the number of boxes by the number of pencils in each box. Alejandro has 3 boxes and each box has 120 pencils. So, 3 * 120 = 360. Therefore, Alejandro has 360 pencils in total.

Stella is working on her family's ranch in Texas, where they raise cattle. She has 4,582 pounds of feed stored for the cows.

1. 3 ✓
2. 2
3. 4
4. 1

Why: First, we subtract the used feed from the total: 4,582 - 1,200 = 3,382. The hundreds place in 3,382 is 3, which represents 3 hundreds (or 300). Therefore, the correct answer is 3.
