Answer:

2,500 pages

Step-by-step explanation:

Let

y -----> the overall cost

x -----> the number of pages

we know that

HP printer

y=0.03x+180 ------> equation A

Samsung printer

y=0.01x+230 -----> equation B

Solve the system by substitution

Substitute equation B in equation A

0.03x+180=0.01x+230

Solve for x

0.03x-0.01x=230-180\\0.02x=50\\x=2,500\ pages
