To own and operate a poster printer, it costs $250 for the printer and an additional $0.20 per poster for ink. To print out posters at a print store, it costs $1 per poster. Let p represent the number of posters. When will the cost for owning and operating a poster printer equal the cost for printing at a print store?

312.5

Step-by-step explanation:

Since it is $250 plus 20 cents per poster, the equation is 0.20p+250. It is $1 per poster at store and you want to know when the cost is going to be the same so you set them equal to each other.

0.20p+250=p

250=0.80p

312.5=p

30005

yes ok
