Clint |
| Before |
11 u |
7 u |
10 u |
| Change |
+ 0.2 u |
+ 2.8 u |
- 3 u |
| After |
11.2 u |
9.8 u |
7 u |
Number of coins that Clint gave to Zeph and Tommy
=
310 x 10 u
= 3 u
Number of coins that Tommy received from Clint
=
40100 x 7 u
= 2.8 u
Number of coins that Zeph received from Clint
= 3 u - 2.8 u
= 0.2 u
Number of less coins that Clint had less than Zeph
= 11.2 u - 7 u
= 4.2 u
4.2 u = 84
1 u = 84 ÷ 4.2 = 20
Number of coins that Zeph and Clint had
= 11.2 u + 7 u
= 18.2 u
= 18.2 x 20
= 364
Answer(s): 364
