Several customers order small fruit baskets filled with apples, bananas, and oranges. Let a represent the price per pound of apples, b represent the price per pound of bananas, and c represent the price per pound of oranges. The system represents the number of pounds of each type of fruit and the total price of each fruit basket. How much per pound does each type of fruit cost? apples: $2.00/lb, bananas: $0.50/lb, and oranges: $3.00 apples: $2.00, bananas: $1.50/lb, and oranges: $3.00/lb apples: $2.50/lb, bananas $0.25/lb, and oranges: $3.00/lb apples: $2.50, bananas: $0.75, oranges: 3.00/lb
a. apples: $2.00/lb, bananas: $0.50/lb, and oranges: $3.00
