#1**+5 **

$$1\ dozen = 12$$

$$1/2 \ dozen = 6$$

**dozen(apples)**

12(3x+6)

36x+72

**1/2dozen(oranges)**

6(4x-5)

24x-30

**dozen apples + 1/2dozen oranges**

(36x+72) + (24x-30)

(36x+24x) + (72-30)

60x + 42

So our answer is **60x + 42 pesos**.

If we knew the value of x, we could find the exact cost. We don't though, so this is our final answer.
