Tracksuit 5460

The tracksuit became cheaper by 15% later on sale and later by 10%. How many euros did Janka save if she bought this set after the second discount and paid € 45.9?

Correct answer:

x =  14.1 Eur

Step-by-step explanation:


c · (1-15/100)·(1-10/100) = 45.90
x = c - 45.90

76.5c = 4590
c-x = 45.9

Row 2 - 1/76.5 · Row 1 → Row 2
76.5c = 4590
-x = -14.1


x = -14.1/-1 = 14.1
c = 4590/76.5 = 60

c = 60
x = 141/10 = 14.1
