B1. From the given price list, determine:

(A) How much does $1 \mathrm{~kg}$ of rye bread cost?

(B) How much does $\frac{1}{4} \mathrm{~kg}$ of black bread cost?

(C) How much cottage cheese can you get for 200 SIT?

(B) How much do you pay for $\frac{1}{4} \mathrm{~kg}$ of rye bread, 10 dag of edam cheese, and $\frac{1}{2} \mathrm{~kg}$ of graham bread?

| product | quantity | price |
| :---: | :---: | :---: |
| BREAD | kg | SIT |
| white | 1 | 95 |
| black | 1 | 90 |
| rye | $\frac{1}{2}$ | 48 |
| graham | $\frac{1}{4}$ | 20 |


| product | quantity | price |
| :---: | :---: | :---: |
| CHEESES | kg | SIT |
| cottage | 1 | 800 |
| trapist | $\frac{1}{2}$ | 370 |
| edam | $\frac{1}{4}$ | 175 |
B1. (A) If $\frac{1}{2} \mathrm{~kg}$ of rye bread costs 48 SIT, then $1 \mathrm{~kg}$ of this bread costs $2 \cdot 48=96$ SIT.

(B) If $1 \mathrm{~kg}$ of black bread costs 90 SIT, then $\frac{1}{4} \mathrm{~kg}$ costs $\frac{90}{4}=22.5$ SIT.

(C) If 800 SIT buys $1 \mathrm{~kg}$ of cottage cheese, then 200 SIT buys $\frac{200}{800}=\frac{1}{4} \mathrm{~kg}$.

(D) For $\frac{1}{4} \mathrm{~kg}$ of rye bread, we pay $\frac{1}{2} \cdot 48=24$ SIT, for 10 dag of edam cheese $\frac{100}{250} \cdot 175=70$ SIT, for $\frac{1}{2} \mathrm{~kg}$ of graham bread $2 \cdot 20=40$ SIT, so in total we pay 134 SIT.
