Question

You buy 1.95 pounds of oranges and 1.65 pounds of apples. Oranges and apples sell for the same price per pound. The total​ cost, after using a 75¢​-off ​coupon, is ​$2.49. If c represents the cost of the fruit in dollars per​ pound, what equation could you use to find the value of​ c?

Answer 1

(1.95 +1.65)c -0.75 = 2.49

Explanation:

The cost of the fruit is the cost per pound (c) multiplied by the number of pounds, 1.95 +1.65. After $0.75 is deducted, the total cost is $2.49. The equation that says this is ...

(1.95 +1.65)c -0.75 = 2.49

__

3.6c = 3.24 . . . . add 0.75, simplify

c = 0.9 . . . . . . divide by the coefficient of c

The cost of the fruit is $0.90 per pound.
