Make p the same.
(2)x2 = (3) |
| Before |
5 u |
1 u |
2 u |
| Change |
+ 222 |
+ 339 |
+ 678 |
| After |
2 p |
1 p |
2 p |
5 u + 222 =
2 p --- (1)
1 u + 339 = 1 p --- (2)
(2)
x2
2 u + 678 =
2 p --- (3)
(1) = (3)
5 u + 222 = 2 u + 678
5 u - 2 u = 678 - 222
3 u = 456
1 u = 456 ÷ 3 = 152
Total amount raised by both schools in the first week
= 5 u + 1 u
= 6 u
= 6 x 152
= $912
Total amount of money raised in 2 weeks by the two schools
= 912 + 222 + 339
= $1473
Answer(s): $1473
