peanut butter granola bars

Answer 1

Answer: an estimate for the number of peanut butter granola bars in the backpack is 15.

Explanation:

Jaylen handed out a total of 2 + 1 + 4 + 3 = 10 granola bars.

Of those, 3 are peanut butter flavored.

We can set up a proportion to estimate how many peanut butter granola bars are in the backpack:

3 peanut butter bars / 10 total bars = x peanut butter bars / 50 total bars

Solving for x, we get:

x = 3/10 * 50

x = 15

Therefore, an estimate for the number of peanut butter granola bars in the backpack is 15.
