Jean spent ²₁₃ of her money on some folders. She spent ⁴₁₁ of the remaining money on some post-it pads and ⁴₇ of what was left on some foolscaps.

1. What fraction of her money was spent on foolscaps?
2. Given that the folders cost $14 less than the foolscaps, find the sum of money that Jean spent.

Folders	Remaining money
2	11
	Post-it Pads	Left
	4	7
		Foolscaps	Rest
2 u	4 u	4 u	3 u

(a)
Fraction of money left after spending on the folders
= 1 - ²₁₃
= ¹¹₁₃

Fraction of remaining money after spending on the post-it pads
= 1 - ⁴₁₁
= ⁷₁₁

Fraction of what was left after spending on the foolscaps
= 1 - ⁴₇
= ³₇

Fraction of money that was spent on foolscaps = ⁴₁₃

(b)
Amount that Jean spent on the folders = 2 u
Amount that Jean spent on the foolscaps = 4 u

Amount that the folders cost less than the foolscaps
= 4 u - 2 u
= 2 u

2 u = 14

1 u = 14 ÷ 2 = 7

Amount that Jean sent
= 2 u + 4 u + 4 u
= 10 u
= 10 x 7
= $70

Answer(s): (a) ⁴₁₃; (b) $70
