Palka 14933

Palka Ball costs a total of € 1.10
A pen costs one euro more than a ball.
How much is the ball?

Correct answer:

l =  0.05 Eur

Step-by-step explanation:


p+l=1.10
p=1+l

l+p = 1.1
l-p = -1

Row 2 - Row 1 → Row 2
l+p = 1.1
-2p = -2.1


p = -2.1/-2 = 1.05
l = 1.1-p = 1.1-1.05 = 0.05

l = 1/20 = 0.05
p = 21/20 = 1.05
