Make p the same.
(2)x3 = (3) |
| Before |
5 u |

| Change |
+ 325 |
+ 287 |
+ 861 |
| After |
3 p |
1 p |
3 p |
5 u + 325 =
3 p --- (1)
1 u + 287 = 1 p --- (2)
(2)
x3
3 u + 861 =
3 p --- (3)
(1) = (3)
5 u + 325 = 3 u + 861
5 u - 3 u = 861 - 325
2 u = 536
1 u = 536 ÷ 2 = 268
Total amount raised by both teams in the first week
= 5 u + 1 u
= 6 u
= 6 x 268
= $1608
Total amount of money raised in 2 weeks by the two teams
= 1608 + 325 + 287
= $2220
Answer(s): $2220
