Make p the same.
(2)x2 = (3) |
| Before |

| Change |
+ 315 |
+ 321 |
+ 642 |
| After |
2 p |
1 p |
2 p |
5 u + 315 =
2 p --- (1)
1 u + 321 = 1 p --- (2)
(2)
x2
2 u + 642 =
2 p --- (3)
(1) = (3)
5 u + 315 = 2 u + 642
5 u - 2 u = 642 - 315
3 u = 327
1 u = 327 ÷ 3 = 109
Total amount raised by both schools in the first week
= 5 u + 1 u
= 6 u
= 6 x 109
= $654
Total amount of money raised in 2 weeks by the two schools
= 654 + 315 + 321
= $1290
Answer(s): $1290
