| |
Glen |
Peter |
Curry |
| Before |
11 u |
7 u |
4 u |
| Change |
+ 2.1 u |
+ 0.7 u |
- 2.8 u |
| After |
13.1 u |
7.7 u |
1.2 u |
Number of coins that Curry gave to Glen and Peter
=
710 x 4 u
= 2.8 u
Number of coins that Peter received from Curry
=
10100 x 7 u
= 0.7 u
Number of coins that Glen received from Curry
= 2.8 u - 0.7 u
= 2.1 u
Number of less coins that Curry had less than Glen
= 13.1 u - 1.2 u
= 11.9 u
11.9 u = 119
1 u = 119 ÷ 11.9 = 10
Number of coins that Glen and Curry had
= 13.1 u + 1.2 u
= 14.3 u
= 14.3 x 10
= 143
Answer(s): 143
