Charlie saves $20.
Adam saves 10 times as much money as Charlie.
- How much does Adam save?
- How much does Adam save more than Charlie?
- How much does Charlie 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 Charlie saves = 1 u
Amount that Adam saves = 10 u
1 u = 20
Amount that Adam saves
= 10 u
= 10 x 20
= $200
(b)
Amount that Adam saves more than Charlie
= 10 u - 1 u
= 9 u
= 9 x 20
= $180
(c)
Amount that Charlie saves less than Adam
= 10 u - 1 u
= 9 u
= 9 x 20
= $180
(d)
Total amount that both of them save altogether
= 1 u + 10 u
= 11 u
= 11 x 20
= $220
Answer(s): (a) $200; (b) $180; (c) $180; (d) $220
