How do I figure this: A lunch bill is unknown. J has $8.00; not enough for the total bill. H. pays 3/5 of the bill. How much does H. pay? What's the total bill?

(2/5)L = 8

L = 8 / (2/5)

L = 8 * (5/2)

L = 40/2

L = 20

The total lunch bill is $20.

data is not clear.

Are you saying that J pays his $8 towards the bill?

Let the total bill be x dollars

8 + (3/5)x = x

times 5

40 + 3x = 5x

40 = 2x

x = 20

the bill was $20

check:

H pays 3/5 of that = 12

J pays 8, for a total of 20
