Sabrina spent ¹₁₁ of her money on some markers. She spent ³₁₀ of the remaining money on some pens and ³₇ of what was left on some correction tapes.

1. What fraction of her money was spent on correction tapes?
2. Given that the markers cost $14 less than the correction tapes, find the sum of money that Sabrina spent.

Markers	Remaining money
1	10
	Pens	Left
	3	7
		Correction Tapes	Rest
1 u	3 u	3 u	4 u

(a)
Fraction of money left after spending on the markers
= 1 - ¹₁₁
= ¹⁰₁₁

Fraction of remaining money after spending on the pens
= 1 - ³₁₀
= ⁷₁₀

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

Fraction of money that was spent on correction tapes = ³₁₁

(b)
Amount that Sabrina spent on the markers = 1 u
Amount that Sabrina spent on the correction tapes = 3 u

Amount that the markers cost less than the correction tapes
= 3 u - 1 u
= 2 u

2 u = 14

1 u = 14 ÷ 2 = 7

Amount that Sabrina sent
= 1 u + 3 u + 3 u
= 7 u
= 7 x 7
= $49

Answer(s): (a) ³₁₁; (b) $49
