m is an unknown. Think of it as 1 unit.
$ (5m + 6) is left in the end.
This is equal to $81.
So the question wants you to solve for m.
5m + 6 = 81
So 5m = 81 - 6
5m = 75
m = 75 ÷ 5
m = 15
$ she had at first
= $3m
= $(3 × 15)
= $45
$ (5m + 6) is left in the end.
This is equal to $81.
So the question wants you to solve for m.
5m + 6 = 81
So 5m = 81 - 6
5m = 75
m = 75 ÷ 5
m = 15
$ she had at first
= $3m
= $(3 × 15)
= $45
