Charlie saves $20.
Adam saves 3 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 = 3 u
1 u = 20
Amount that Adam saves
= 3 u
= 3 x 20
= $60
(b)
Amount that Adam saves more than Charlie
= 3 u - 1 u
= 2 u
= 2 x 20
= $40
(c)
Amount that Charlie saves less than Adam
= 3 u - 1 u
= 2 u
= 2 x 20
= $40
(d)
Total amount that both of them save altogether
= 1 u + 3 u
= 4 u
= 4 x 20
= $80
Answer(s): (a) $60; (b) $40; (c) $40; (d) $80
