Gavin and John have $150 altogether. John has $46 less than Gavin. How much money does Gavin have?

Answer 1

150/2 = 75
46/2 = 13
Gavin = 75 +13 = 88
John = 75 - 13 = 62

Answer 2

150/2 = 75
46/2 = 23
Gavin = 75 +23 = 98
John = 75 - 23 = 52

Answer 3

or .... in a more direct way:

amount for Gavin ---- x
amount for John = x-46

x +x-46 = 150
2x = 196
x = 98

So Gavin has $98 and John has 98-46 or $52
