Four cake decorators can decorate 24 cupcakes in 10 minutes. If the bakery gets an order for 90 cupcakes that need to be ready in 15 minutes, then how many cake decorators do they need to have the cupcakes ready to go on time?

Answer 1

Below

Explanation:

24 cc / (10 min * 4 p) = .6 cc/ (min p)

90 cc / (15min *x p) = .6

90 = 9x

x =10 people

Answer 2

Explanation:

4 decorators can make 24 cupcakes is 10 minutes. so if we divide 24 by 4 we can find how cupcakes 1 decorator can make in 10 minutes.

= 6

If we need to be ready in fifteen minutes and we make cupcakes in 10 we can multiply 6 by 1.5.

1 decorator can make 9 cupcakes in 15 minutes.

We need 90 cupcakes. 9 X 10 = 90 cupcakes.

How many cake decorators do they need to have the cupcakes ready to go on time?.

You need 10 cake decorators to make 90 cupcakes in 15 minutes.
