Answer:
-40 < x < 20
Step-by-step explanation:
step 1: -12 < 1/2(x+16) < 18 --> Distribute
step 2: -12 < 1/2x + 8 < 18 --> subtract 8
step 3: -20 < 1/2x < 10 --> Multiply by 2
answer : -40 < x < 20
Take 4,000 times 12 to get 48,000. that’s how much A costs.
B is a little harder. you have to take (2,300+300)x12+(4*250). this equals $32,100
the correct answer would be B.
