Question

jen and heather went to lunch. when the bill came jen discovered she had only $6 luckily heather had enough money to pay the other part, or 3/5 of the bill.
how much did heather pay?
how much was the bill?

Answer 1

Let x = the amount of the bill. Then we are told that $6 is 2/5 of the bill.
Well not exactly we were told that Heather paid 3/5 of the bill so Jenn had to pay 2/5.

Answer 2

$6 = (2/5)(x). Solve for x and get the total bill.
