Michael has thrice as many coins as Flynn. Flynn has 5 more coins than Albert. They have a total of 150 coins.
- How many coins does Michael have?
- How many coins does Albert have?
(a)
Number of coins that Flynn has = 1 u
Number of coins that Albert has = 1 u - 5
Number of coins that Michael has = 3 u
Total number of coins
= 1 u + 1 u - 5 + 3 u
= 5 u - 5
5 u - 5 = 150
5 u = 150 + 5
5 u = 155
1 u = 155 ÷ 5 = 31
Number of coins that Michael has
= 3 u
= 3 x 31
= 93
(b)
Number of coins that Albert has
= 1 u - 5
= 31 - 5
= 26
Answer(s): (a) 93; (b) 26
