The value of Joshua's money is $44, this is so because we have to substract from the excess that Brandon has to get Joshua's value
Given Data
Brandon
10 dollar bill 7 pieces = 10*7 = $70
1 dollar bill 8 pieces = 1*8 = $8
The total money that Brandon has is 70+8 = $78
We know that Joshua has 3 fewer ten-dollar bills and 4 fewer one-dollar bills than Brandon
Joshua
10 dollar bill 4 pieces = 10*4 = $40
1 dollar bill 4 pieces = 1*4 = $4
The total money that Joshua has is 40+4 = $44
