Answer:
$2.40
Step-by-step explanation:
If we know it is $1.08 to make 18 copies. We can do the math to find the rate of 1 copy. This would be by doing 1.08/18=0.06. So, it costs $0.06 to make 1 copy. Now, multiply that by 40 copies 0.06x40=2.40. The cost of 40 copies is $2.40.

Answer:
y = -x - 3
Step-by-step explanation:
