Adam saves $90.
Charlie saves 4 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 = 4 u
1 u = 90
Amount that Charlie saves
= 4 u
= 4 x 90
= $360
(b)
Amount that Charlie saves more than Adam
= 4 u - 1 u
= 3 u
= 3 x 90
= $270
(c)
Amount that Adam saves less than Charlie
= 4 u - 1 u
= 3 u
= 3 x 90
= $270
(d)
Total amount that both of them save altogether
= 1 u + 4 u
= 5 u
= 5 x 90
= $450
Answer(s): (a) $360; (b) $270; (c) $270; (d) $450
