Cody has four times as many erasers as Oscar. Oscar has 6 more erasers than Henry. They have a total of 102 erasers.
- How many erasers does Cody have?
- How many erasers does Henry have?
(a)
Number of erasers that Oscar has = 1 u
Number of erasers that Henry has = 1 u - 6
Number of erasers that Cody has = 4 u
Total number of erasers
= 1 u + 1 u - 6 + 4 u
= 6 u - 6
6 u - 6 = 102
6 u = 102 + 6
6 u = 108
1 u = 108 ÷ 6 = 18
Number of erasers that Cody has
= 4 u
= 4 x 18
= 72
(b)
Number of erasers that Henry has
= 1 u - 6
= 18 - 6
= 12
Answer(s): (a) 72; (b) 12
