4. Marko bought $3 \mathrm{~kg}$ of apples, $2 \mathrm{~kg}$ of pears, and $1 \mathrm{~kg}$ of strawberries at the market. He paid 59 kn for all the fruit. Apples are cheaper than pears by $1 \mathrm{kn}$ and 50 lp per kilogram, and they are three times cheaper than strawberries per kilogram. How much does one kilogram of pears cost?
First method:

Apples are the cheapest, so the following applies:

$8 \square + 3 = 59 \quad 1$ POINT

$8 = 59 - 3 \quad 1$ POINT

$8 \square = 56 \quad 1$ POINT

$\square = 56 : 8 = 7 \quad 1$ POINT

One kilogram of pears costs $7 \text{kn} + 1 \text{kn} 50 \text{lp} = 8 \text{kn} 50 \text{lp}$ 1 POINT

TOTAL 10 POINTS
