Gabriel |
Charlie |
Christopher |
Before |
8 u |
9 u |
6 u |
Change |
+ 0.6 u |
+ 3.6 u |
- 4.2 u |
After |
8.6 u |
12.6 u |
1.8 u |
Number of buttons that Christopher gave to Gabriel and Charlie
=
710 x 6 u
= 4.2 u
Number of buttons that Charlie received from Christopher
=
40100 x 9 u
= 3.6 u
Number of buttons that Gabriel received from Christopher
= 4.2 u - 3.6 u
= 0.6 u
Number of less buttons that Christopher had less than Gabriel
= 8.6 u - 1.8 u
= 6.8 u
6.8 u = 272
1 u = 272 ÷ 6.8 = 40
Number of buttons that Gabriel and Christopher had
= 8.6 u + 1.8 u
= 10.4 u
= 10.4 x 40
= 416
Answer(s): 416
