Dana received $80 more pocket money than Zoe each month. Both of them spent $190 per month and saved the rest. After a few months, Dana saved $1560 but Zoe only saved $1320.

1. What was Dana's monthly pocket money?
2. Zoe wanted to save a total of $2200. How many more months did she need in order to save this amount?

(a)
Total amount that Dana saved more than Zoe
= 1560 - 1320
= $240

Number of months taken for each of them to save their amounts
= 240 ÷ 80
= 3

Amount that Dana saved each month
= 1560 ÷ 3
= $520

Dana's monthly pocket money
= 520 + 190
= $710

(b)
Zoe's monthly pocket money
= 710 - 80
= $630

Amount that Zoe saved each month
= 630 - 190
= $440

Remaining amount that Zoe needed to save
= 2200 - 1320
= $880

Number of more months that Zoe needed to save the remaining $880
= 880 ÷ 440
= 2

Answer(s): (a) $710; (b) 2
