| Before |
11 u |
10 u |
10 u |
| Change |
+ 0.5 u |
+ 7 u |
- 7.5 u |
| After |
11.5 u |
17 u |
2.5 u |
Number of coins that Curry gave to Seth and Fabian
=
34 x 10 u
= 7.5 u
Number of coins that Fabian received from Curry
=
70100 x 10 u
= 7 u
Number of coins that Seth received from Curry
= 7.5 u - 7 u
= 0.5 u
Number of less coins that Curry had less than Seth
= 11.5 u - 2.5 u
= 9 u
9 u = 450
1 u = 450 ÷ 9 = 50
Number of coins that Seth and Curry had
= 11.5 u + 2.5 u
= 14 u
= 14 x 50
= 700
Answer(s): 700
