Charlie saves $30.
Adam saves 4 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 = 4 u
1 u = 30
Amount that Adam saves
= 4 u
= 4 x 30
= $120
(b)
Amount that Adam saves more than Charlie
= 4 u - 1 u
= 3 u
= 3 x 30
= $90
(c)
Amount that Charlie saves less than Adam
= 4 u - 1 u
= 3 u
= 3 x 30
= $90
(d)
Total amount that both of them save altogether
= 1 u + 4 u
= 5 u
= 5 x 30
= $150
Answer(s): (a) $120; (b) $90; (c) $90; (d) $150
