Manuel bought 9 pounds of apples. he has eaten 3/4 of a pound so far and has $15 worth of apples left. write and solve an equation to find the cost of the apples per pound to the nearest dollar. how much did the apples cost per pound?

We can form a ratio equation. the ratio would be the amount of original apples to the cost versus the new amount of apples and new cost. we know all amounts except original cost.

pounds/cost = new pounds/new cost

9/x = (3/4)9 / 15

9/x = (27/4) / 15

9/x = 27/60

9/x = 9/20

cross multiply

9x = 180
x = 20

40 because it’s just a little longer than 32 feet
