Question

Can someone help me with some math? I completely forgot how to do this. Essentially, I have to figure out which cookie is the cheapest based on the number of chips and what the price per chocolate chip is.
Brand #1 – Simply Made: $ 2.50/20 cookies
Brand #2 – Chips Deluxe: $ 2.50 /24 cookies
Brand #3 – Chips Ahoy: $ 3.50/45 cookies
Brand #4 – Great Value: $ 2.00/36 cookies
Simply Made has 27 chocolate chips per cookie

Chips Deluxe has 26.5 chocolate chips per cookie

Chips Ahoy has 24.6 chocolate chips per cookie

Great Value has 19.5 chips per cookie

Answer 1

First divide all the prices by the amount of cookies it gets. so for example, for brand #1, you'd do 2.5/20

Answer 2

Which gives me .13 cents per cookie. Right?

Answer 3

@StudyGurl14 How do I figure out how to do the chips?

Answer 4

right, now divide that by the amount of chips per cookie for that brand

Answer 5

and actually, it'd be 0.125 per cookie, not .13

Answer 6

.0046? I rounded up.

Answer 7

yes.

Answer 8

Just repeat with all the rest.

Answer 9

make sure to record all this too, so you can easily compare them when you're done

Thank you so much! I was pretty sure that was how to do this, but this is pretty basic math and it has been so long since I've done it.
