Salid bought 35 feet of window trim at a hardware store. The trim cost $1.75 per foot, including sales tax. If salid paid with a $100.00 bill, how much change should he have received?

Answers

first we have to write down what we know and that is 35ft of window trim is what he has and for each foot of the 35 is a $1.75. so-->35(1.75)--> this is 61.25 or $61.25. He used 100.00 to pay so he did not use all of the 100. 100-61.25= is how much salid should recieve back which is $38.75.

If you would like to know how much change should Salid have received, you can calculate this using the following steps:

35 feet * $1.75 per foot = 35 * 1.75 = $61.25

$100.00 - $61.25 = $38.75

Result: Salid should have received $38.75.
