jen and heather went to lunch. when the bill came, jen discovered that she had only eight dollars. luckily heather had enough money to pay the other part, or three fifth of the bill.
how much did heather pay?
how much was the total bill?

was the eight dollars 1/5 of the bill? Seems like you are missing info.

no shanta this is how it is written

Since 2/5 = 0.4 . . .
Let x = total bill.
0.4x = 8
x = 8/0.4
x = 20 
I would say 20 dollars. Because if Jen had 8 dollars that must have been 2/5 of the bill which would make 1/5 4 dollars and 4 x 5 = 20.
