Question

At Sammy's Bakery, customers can purchase 13 cookies for $12.87. If a customer has only $4.50

to spend, what is number of cookies they can purchase?

Answer 1

First we set up the equation
12.87x = 13
With the x meaning the amount of purchases
Now we can isolate c
12.87x/12.87 = 13/12.87
x = 1.0101…
Therefore the ratio to money to cookies is x
So 1.0101..(4.50) = 4.5454…
So they can purchases 4 cookies
