Sweaters 8377

The store earned CZK 1,950 for 13 jackets and five sweaters of the same size and quality. The sweater was 350 CZK cheaper than the jacket. Find the price of the jacket and sweater.

Correct answer:

b =  1200
s =  850

Step-by-step explanation:


13b+5s = 19850
s = b - 350

13·b+5·s = 19850
s = b - 350

13b+5s = 19850
b-s = 350

Row 2 - 1/13 · Row 1 → Row 2
13b+5s = 19850
-1.38s = -1176.92


s = -1176.92307692/-1.38461538 = 850
b = 19850-5s/13 = 19850-5 · 850/13 = 1200

b = 1200
s = 850
