Jean received $30 more pocket money than Kylie each month. Both of them spent $130 per month and saved the rest. After a few months, Jean saved $1680 but Kylie only saved $1320.

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

(a)
Total amount that Jean saved more than Kylie
= 1680 - 1320
= $360

Number of months taken for each of them to save their amounts
= 360 ÷ 30
= 12

Amount that Jean saved each month
= 1680 ÷ 12
= $140

Jean's monthly pocket money
= 140 + 130
= $270

(b)
Kylie's monthly pocket money
= 270 - 30
= $240

Amount that Kylie saved each month
= 240 - 130
= $110

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

Number of more months that Kylie needed to save the remaining $880
= 880 ÷ 110
= 8

Answer(s): (a) $270; (b) 8
