Help thanks ASAP ASAP number 7

Step-by-step explanation:

5 computers = $140

10 computers = $200

15 computers = $260

Common difference = $60 for every 5 computer, $12 for 1 computer.

let cost of x no of computers be c.

forming an equation,

c = (x - 5) x 12 + 140

hence, to ship 84 computer,

c = (84 - 5) x 12 + 140

c = 1088

thus answer is option B.
