Margo can purchase tile at a store for $0.79 per tile and rent a tile saw for $24.at another store she can barrow the tile saw for free if she buys tiles there for $1.19 per tile. how many tiles must she buy for the cost to be the same at both stores?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
