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:
560 m
Step-by-step explanation:
Jill's distance is given as 250 m.
John's distance can be computed as ...
distance = speed × time = (70 m/min)(3 min) = 210 m
Suzy's distance is given as 100 m.
Then the total distance is ...
250 m + 210 m + 100 m = 560 m
The distance traveled is 560 m in this relay.
Answer:
Step-by-step explanation:
2x = 100
2x=100. Divide two on each side
X= 50
4k+mn=n-3
