Answer:
The third option is correct i.e. 15 x + 30 y minus 220.
Step-by-step explanation:
We have to choose expression from the option that is equivalent to
[tex]30(\frac{1}{2}x - 2) + 40(\frac{3}{4}y - 4)[/tex]
Now, [tex]30(\frac{1}{2}x - 2) + 40(\frac{3}{4}y - 4)[/tex]
= 15x - 60 + 30y - 160
= 15x + 30y - 220
Therefore, the third option is correct i.e. 15 x + 30 y minus 220. (Answer)
