One brand of plastic garbage bags costs $8.99 for 45 bags. A second brand costs $7.75 for 32 bags. If you have a savings coupon for $0.25 for the second brand, which brand will be cheaper per bag?

Respuesta :

The first brand is cheaper.

Answer: Brand A is cheaper per bag

Step-by-step explanation:

First brand:

45 bags cost $8.99

A bag will cost $8.99/45 = $0.1998

Second brand:

32 bags cost $7.75

A bag will cost $7.75/32= $0.242

But a saving coupon of $0.25 for second brand

So $7.75-$0.25= $7.50

And $7.50/32 =$ 0.234

From the above calculation.. brand a is cheaper .
