When a () is right next to a number such as the problem you have it means to multiply. so 77 times -1 equals -77. so i'm not sure why -77 isn't one of your answer choices. maybe you mistyped something?
The answer is C (Length=32 feet and Width=24 feet)
If im doing right....
100,000*.5=50,000
Then 12,000+50,000=62,000 per year.

1 = 2/2
Therefor if we multiply 9/5 by 2/2 we will get 18/10
Basically figure out what denominator you need and then find a suitable value of 1, where in this case 5*2 = 10 :)
