Charlie saves $80.
Adam saves 9 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 = 9 u
1 u = 80
Amount that Adam saves
= 9 u
= 9 x 80
= $720
(b)
Amount that Adam saves more than Charlie
= 9 u - 1 u
= 8 u
= 8 x 80
= $640
(c)
Amount that Charlie saves less than Adam
= 9 u - 1 u
= 8 u
= 8 x 80
= $640
(d)
Total amount that both of them save altogether
= 1 u + 9 u
= 10 u
= 10 x 80
= $800
Answer(s): (a) $720; (b) $640; (c) $640; (d) $800
