Answer:
The third option is correct i.e. 15 x + 30 y minus 220.
Explanation:
We have to choose expression from the option that is equivalent to
30(\fraction{1}{2}x - 2) + 40(\fraction{3}{4}y - 4)
Now, 30(\fraction{1}{2}x - 2) + 40(\fraction {3}{4}y - 4)
= 15x - 60 + 30y - 160
= 15x + 30y - 220
With that being said, the third option is correct i.e. 15 x + 30 y minus 220.
