Jade spent ²₉ of her money on some post-it pads. She spent ²₇ of the remaining money on some rulers and ⁴₅ of what was left on some markers.

1. What fraction of her money was spent on markers?
2. Given that the post-it pads cost $18 less than the markers, find the sum of money that Jade spent.

Post-it Pads	Remaining money
2	7
	Rulers	Left
	2	5
		Markers	Rest
2 u	2 u	4 u	1 u

(a)
Fraction of money left after spending on the post-it pads
= 1 - ²₉
= ⁷₉

Fraction of remaining money after spending on the rulers
= 1 - ²₇
= ⁵₇

Fraction of what was left after spending on the markers
= 1 - ⁴₅
= ¹₅

Fraction of money that was spent on markers = ⁴₉

(b)
Amount that Jade spent on the post-it pads = 2 u
Amount that Jade spent on the markers = 4 u

Amount that the post-it pads cost less than the markers
= 4 u - 2 u
= 2 u

2 u = 18

1 u = 18 ÷ 2 = 9

Amount that Jade sent
= 2 u + 2 u + 4 u
= 8 u
= 8 x 9
= $72

Answer(s): (a) ⁴₉; (b) $72
