Question

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

Answer 1

She must by 60 tiles for the prices to be even. 24+0.79x=1.19x x=amount of tiles. you subtract 0.79x from both sides. you should get 24=0.4x. then you divide 0.4 from both sides. you should get 60=x
