Answer:100
Step-by-step explanation:
Option B is the correct answer.
3 is greater than -5, -9, and -1.
Hint: Remember to distribute the negative when solving. A negative directly outside outside of and to the left the parenthesis times a negative number inside the parenthesis makes that number positive.
So for option B, you can simplify it to -3 +4 +2. And that equals 3.
A) -3+-4-(-2) = -5
B) -3-(-4)-(-2) = 3
C) -3+(-4)-2 = -9
D) -3-(-4)-2 = -1

let x be the total number of hours
Amazing design total charge = 45x+250
super structures total charge = 60x+100
both companies charge the same amount when both equation equals

15x=150
x=10
therefore at 10 hours both companies will charge the same amount
