Andy had
112 as many cards as Luke. Luke had thrice as many cards as Paul. If Andy had 66 cards fewer than Paul,
- how many cards did Andy have?
- how many cards did they have altogether?
(a)
Number of cards that Andy had = 1 u
Number of cards that Luke had = 12 u
Number of cards that Paul had = 12 u ÷ 3 = 4 u
Number of cards that Andy had fewer than Paul
= 4 u - 1 u
= 3 u
3 u = 66
1 u = 66 ÷ 3 = 22
Number of cards that Andy had
= 1 u
= 22
(b)
Total number of cards that they had
= 1 u + 12 u + 4 u
= 17 u
= 17 x 22
= 374
Answer(s): (a) 22; (b) 374
