Suit

The suit cost 119 euros. How much cost the pants if it is 50% cheaper than the jacket?

Correct answer:

a =  39.6667 Eur

Step-by-step explanation:


a+b = 119
a = (1-50/100) b

a+b = 119
a = (1-50/100)·b

a+b = 119
100a-50b = 0

Pivot: Row 1 ↔ Row 2
100a-50b = 0
a+b = 119

Row 2 - 1/100 · Row 1 → Row 2
100a-50b = 0
1.5b = 119


b = 119/1.5 = 79.33333333
a = 0+50b/100 = 0+50 · 79.33333333/100 = 39.66666667

a = 119/3 ≈ 39.666667
b = 238/3 ≈ 79.333333
