Respuesta :

Chips ahoy $0.18 per oz.

1) Let's write it down, since the point here is what's the best deal we need to find out the unit rate for each one. Let's set a proportion:

$2.98 ----------- 15.5 oz

x -------------- 1 oz

Cross multiplying it:

15.5x = 2.98 * 1 Divide both sides by 15.5

x= 0.192

So $0.19 per oz.

Chips Ahoy:

$2.50------------14 oz

y --------------1

14y= 2.50

y=0.1785 rounding it to the nearest hundredth 0.18

Then $0.18 per oz

So the better deal, is buying Chips Ahoy.
