Company A rents copy machines for $300 a month plus $0.05 per copy. Company B charges $600 a month plus $0.01 per copy. For which number of copies do the two companies charge the same amount?

7,500 copies

Step-by-step explanation:

First, write the problems as equations. There will be one variable: copies (c):

Company A: .05c + 300

Company B: .01c + 600

In order to find when the companies charge the same amount, Company A = Company B. Using the transitive property you get:

Company A = Company B

.05c + 300 = .01c + 600

Now, you just need to solve for c:

.05c + 300 = .01c + 600

.05c = .01c + 300

.04c = 300

c = 7,500

In conclusion, the companies will charge the same amount of money when 7,500 copies are made in a month.

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
