Answer:
Total cost = $5.18.
Explanation:
Given the following data;
A pound of banana = $0.60
Quantity of banana = 2.8 pounds
Bag of apples = $3.50
To find the amount spent on banana;
Cost of banana = Quantity of banana * cost of each pound of banana
Cost of banana = 2.8 * 0.6 = $1.68
Total amount spent on banana = $1.68
Therefore, the total amount spent by Andrea on both banana and apples;
Total cost = cost of apple + cost of banana
Total cost = $3.5 + $1.68
Total cost = $5.18.
