A)
Price per an ounce of ice cream before inflating = \$4.79 / 64 = \$ 0.07484
Price per an ounce after inflating : \$3.89 / 48 = 0.08104
Increase in the price = (0.08104 - 0.07484) / 0.07484 = 0.0828
= 0.0828 * 100% = 8.28 %

b)
cost of candy bar per an ounce = \$ 1.29 / 6.8 = \$ 0.1897
cost of candy bar per ounce after reduction in size = \$ 1.29 / 6.4 = \$ 0.2015

Increase in the cost = (\$0.2015 - \$0.1897) / 0.1897 = 0.0622
= 0.0622 * 100% = 6.22 %
