Marion received $80 more pocket money than Zara each month. Both of them spent $110 per month and saved the rest. After a few months, Marion saved $1800 but Zara only saved $1400.

1. What was Marion's monthly pocket money?
2. Zara wanted to save a total of $2240. How many more months did she need in order to save this amount?

(a)
Total amount that Marion saved more than Zara
= 1800 - 1400
= $400

Number of months taken for each of them to save their amounts
= 400 ÷ 80
= 5

Amount that Marion saved each month
= 1800 ÷ 5
= $360

Marion's monthly pocket money
= 360 + 110
= $470

(b)
Zara's monthly pocket money
= 470 - 80
= $390

Amount that Zara saved each month
= 390 - 110
= $280

Remaining amount that Zara needed to save
= 2240 - 1400
= $840

Number of more months that Zara needed to save the remaining $840
= 840 ÷ 280
= 3

Answer(s): (a) $470; (b) 3
