Answer :
Define x:
Let Fred had x dollar.
Fred = x
Greg = x + 17
Solve x :
x + x + 17 = 85
2x + 17 = 85
2x = 68
x = 34
Find the amount each of them had:
Fred = x = $34
Greg = x + 17 = 34 + 17 = $51
Answer: Greg had $51
Let Fred had x dollar.
Fred = x
Greg = x + 17
Solve x :
x + x + 17 = 85
2x + 17 = 85
2x = 68
x = 34
Find the amount each of them had:
Fred = x = $34
Greg = x + 17 = 34 + 17 = $51
Answer: Greg had $51
Greg had $51 while Fred had $34.
Greg has $17 more than Fred: 51-34 = 17
Together, their money is enough to get their mom a present that costs $85 ($51 + $34 = $85)
So Greg have $51.
Greg has $17 more than Fred: 51-34 = 17
Together, their money is enough to get their mom a present that costs $85 ($51 + $34 = $85)
So Greg have $51.
