Adam saves $20.
Charlie saves 7 times as much money as Adam.
- How much does Charlie save?
- How much does Charlie save more than Adam?
- How much does Adam save less than Charlie?
- 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 Charlie saves = 7 u
1 u = 20
Amount that Charlie saves
= 7 u
= 7 x 20
= $140
(b)
Amount that Charlie saves more than Adam
= 7 u - 1 u
= 6 u
= 6 x 20
= $120
(c)
Amount that Adam saves less than Charlie
= 7 u - 1 u
= 6 u
= 6 x 20
= $120
(d)
Total amount that both of them save altogether
= 1 u + 7 u
= 8 u
= 8 x 20
= $160
Answer(s): (a) $140; (b) $120; (c) $120; (d) $160
