Bryan saves $30.
He saves 3 times as much money as Adam.
- How much does Adam save?
- How much does Bryan save more than Adam?
- How much does Adam save less than Adam?
- How much do both of them save altogether?
(a)
Focus on the sentence with the word 'times'.
Assign 1 u to the variable that is found after the word 'times'.
Amount that Adam saves = 1 u
Amount that Bryan saves = 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Adam saves
= 1 u
= $10
(b)
Amount that Bryan saves more than Adam
= 3 u - 1 u
= 2 u
= 2 x 10
= $20
(c)
Amount that Adam saves less than Bryan
= 3 u - 1 u
= 2 u
= 2 x 10
= $20
(d)
Total amount that both of them save altogether
= 1 u + 3 u
= 4 u
= 4 x 10
= $40
Answer(s): (a) $10; (b) $20; (c) $20; (d) $40
