Archie had 3 times as many erasers as Brandon. After Brandon bought another 46 erasers, Archie had twice as many erasers as Brandon. How many erasers did the two boys have altogether in the end?
| |
Archie |
Brandon |
| Before |
3x2 =
6 u |
1x2 =
2 u |
| Change |
|
+ 46 |
| After |
2x3 =
6 u |
1x3 =
3 u |
Number of erasers that Brandon bought
= 3 u - 2 u
= 1 u
1 u = 46
Total number of erasers that the two boys had in the end
= 6 u + 3 u
= 9 u
= 9 x 46
= 414
