You can buy 56 diapers at Babies-R-Us for $28, and you can buy 112 diapers online for $52. Which is the better deal, and how much will you save per diaper?

X would equal about 46 cents

If you buy a diaper online instead of Babies-R-us, you save 4 cents more.

Step-by-step explanation:

If 56 diapers cost 28

then 1 diaper cost x

56x = 28

x = 28/56

x = 0.5 or 50 cents

If 112 diapers cost 52

then 1 diaper cost x

112x = 52

x = 52/112

x = approximately 46 cents.
