Andrea purchased 2.8 pounds of bananas that cost $0.60 per pound
iren [92.7K]

Answer:

Total cost = $5.18.

Step-by-step 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.
