Helen spent $90 on a jumpsuit. She spent ³₁₁ of her remaining money on a skirt and a blazer, after which half her money was left.

1. What fraction of her money did she spend on the jumpsuit?
2. The cost of the blazer is ¹₅ the cost of the skirt. How much more does the skirt cost than the blazer?

Jumpsuit	Remaining amount
	Skirt	Blazer	Left
$90	3		8
1x8			1x8
5 u	3 u		8 u

(a)
The amount of money left is repeated. Make the numerators the same LCM of 1 and 8 is 8. 

1x82x8 of total money = 811 of remaining amount
816 of total money = 811 of remaining amount

Fraction of her money that she spent on the jumpsuit
= ^Jumpsuit_Total 
= ⁵₁₆ 

(b)
Cost of the jumpsuit = 5 u

5 u = 90

1 u = 90 ÷ 5 = 18

Cost of the skirt and the blazer
= 3 u
= 3 x 18
= $54

Cost of the blazer = 1 p
Cost of the skirt = 5 p

Total cost of the blazer and the skirt 
= 1 p + 5 p
= 6 p

6 p = 54

1 p = 54 ÷ 6 = 9

Amount that the skirt was more than the blazer
= 5 p - 1 p
= 4 p
= 4 x 9
= $36

Answer(s): (a) ⁵₁₆; (b) $36
