Question

You purchased 150 feet of chain that normally sells for 0.15 per inch you were charged 22.50 for the sale was the price correct if not what is the correct price an what mistake was made

Answer 1

Correct Answer is 270. Didn't change feet into inches before calculating cause 0.15 times 150 = 22.50

Answer 2

Explanation:

Given length of chain 150 ft

chain sells at 0.15 units per inch

Converting it into per foot

chain sells at
`0.15* 12`=1.8 units per foot

charged price=22.50 units

Actual price=
`1.8* 150`=270 units

Mistake is 247.5 units
