Answer:
d. cost will never be the same
Step-by-step explanation:
power plus: 34.37x + 21
heavy hulk: 34.62x + 33.50 (1/2 fee: 34.62x + 16.75)
*set expressions equal to each other*
34.37x + 21 = 34.62x + 16.75 --> *subtract 34.37x from both sides*
21 = .25x + 16.75 --> *subtract 16.75 from both sides*
4.5 = .25x *divide by .25 on both sides*
18 = x
*find y by plugging in 18 for x*
34.37 (18) + 21 = 34.62 (18) + 16.75
618.66 + 21 = 623.16 + 16.75
639.66 = 639.91
<u><em>they don't equal</em></u>
