Question

Aaron bought 7 packs of balloons for the party. There were 50 balloons in each bag. 40 of the total number of balloons were yellow. How many balloons were not yellow?

Answer 1

310

Explanation:

The equation that we would use to solve this problem is 7 × 50 - 40 = b

(b is the number of non-yellow balloons)

Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.

7 × 50 = 350.

Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.

350 - 40 = 310

Answer 2

`total \: balloons = (50 * 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons`
