Question

You decide to treat yourself to some of your favorite cookies. The box that you bought has 24 cookies. You eat 2 cookies each day as a snack. Which equation shows the number of cookies that you have left at the end of each day?

a.y=-2x+24

b.y=-2x-24

c.y=2x-24

d.y=24x-2

Answer 1

a. y=-2x+24

I got this correct on TTM

Answer 2

a.y=-2x+24

Explanation:

y = the remaining each day

x = the days that passed

∴ every day -2 gets added to your cookies

so lets say 4 days passed after you bought the cookies the equation is:

-2x+24 = (-2) × 4 + 24 = (-8) + 24 = 16
