Answer 8

research cost = -$85,000
inventory cost = -$125,000
sales = +$45,000

net = (-$85,000) + (-$125,000) + (+$45,000) = -$210,000 +$45,000
=-$175,000

They need to gain +$175,000 in sales to break even or have their net = 0.

You said $255,000 suggesting you added all the values together. That suggests you aren't paying attention to your signs.
