Rael has twice as many cards as Jenson. Jenson has 5 more cards than Michael. They have a total of 127 cards.
- How many cards does Rael have?
- How many cards does Michael have?
(a)
Number of cards that Jenson has = 1 u
Number of cards that Michael has = 1 u - 5
Number of cards that Rael has = 2 u
Total number of cards
= 1 u + 1 u - 5 + 2 u
= 4 u - 5
4 u - 5 = 127
4 u = 127 + 5
4 u = 132
1 u = 132 ÷ 4 = 33
Number of cards that Rael has
= 2 u
= 2 x 33
= 66
(b)
Number of cards that Michael has
= 1 u - 5
= 33 - 5
= 28
Answer(s): (a) 66; (b) 28
