Question

Captain Crunch costs $3.50, while a pack of gourmet oatmeal costs $2.50. If $25 of

breakfast food was purchased and 8 total items were purchased, how many oatmeal
packets must have been bought?

Answer 1

I believe the answer is 3

Explanation:

1) 3.50 * 5 = 17.50

2) 2.50 * 3 = 7.50

3) 17.50 + 7.50 = 25

Answer 2

Explanation:

given:

25 = 3.5x + 2.5y

8 = x +y

use substitution to solve

8-x = y

25 = 3.5x + 2.5(8-x)

25 = 3.5x + 20-2.5x

5 = 1x

x = 5

they bought 5 Captain Crunch :P yes, Captain Crunch is sooooo good

and 3 yucky oatmeal packets :P

so 3 packets of oatmeal :)
