Consider this option:
1. formula of perimeter is: P=2(a+b), where a & b - the sides of rectangle.
2. according to the condition 2(x+(x+4))<120; ⇒ x<28
answer: D. x<28
The answer if you need helo with math like this come to me -25
3x-7>2
add 7 to both sides: 3x>9
divide both sides by 3: x>9
16 minutes
0.03*16=0.48
Closest you can get w/out going over.
