Xylia received $50 more pocket money than Gwen each month. Both of them spent $180 per month and saved the rest. After a few months, Xylia saved $1600 but Gwen only saved $1200.

1. What was Xylia's monthly pocket money?
2. Gwen wanted to save a total of $2400. How many more months did she need in order to save this amount?

(a)
Total amount that Xylia saved more than Gwen
= 1600 - 1200
= $400

Number of months taken for each of them to save their amounts
= 400 ÷ 50
= 8

Amount that Xylia saved each month
= 1600 ÷ 8
= $200

Xylia's monthly pocket money
= 200 + 180
= $380

(b)
Gwen's monthly pocket money
= 380 - 50
= $330

Amount that Gwen saved each month
= 330 - 180
= $150

Remaining amount that Gwen needed to save
= 2400 - 1200
= $1200

Number of more months that Gwen needed to save the remaining $1200
= 1200 ÷ 150
= 8

Answer(s): (a) $380; (b) 8
