Make p the same.
(2)x2 = (3) |
| Before |
4 u |
1 u |
2 u |
| Change |
+ 314 |
+ 239 |
+ 478 |
| After |
2 p |
1 p |
2 p |
4 u + 314 =
2 p --- (1)
1 u + 239 = 1 p --- (2)
(2)
x2
2 u + 478 =
2 p --- (3)
(1) = (3)
4 u + 314 = 2 u + 478
4 u - 2 u = 478 - 314
2 u = 164
1 u = 164 ÷ 2 = 82
Total amount raised by both teams in the first week
= 4 u + 1 u
= 5 u
= 5 x 82
= $410
Total amount of money raised in 2 weeks by the two teams
= 410 + 314 + 239
= $963
Answer(s): $963
