Answer:
a. $2.18
b. $15.60
Explanation:
a. Price per pound of American cheese = $4.35 / 0.75 = $5.8
Price per pound of Swiss cheese = $7.98
Difference in price per pound = $7.98 - $5.8 = $2.18
b. Total amount spent on swiss cheese = $7.98 x 2.5 = $19.95
Amount spent more on Swiss cheese than on American cheese = $19,95 - $4.35 = $15.60
