Answer 1

`(3)/(7)+ (1)/(4)+ (1)/(8) = (45)/(56)`
45u=$11
56u=$13.69

Answer 2

The correct answer is ($) 56.

Explanation:

All you have to do is find the common denominator. In this case, 56, because it is divisible by 7, 4, and 8.

You can verify this by setting your target $11 left over.

3/7 of 56 is 24.

1/4 of 56 is 14.

1/8 of 56 is 7.

Add these all together (24+14+7) and you get 45.

56-45 = $11.
