Question

Margo can purchase tile at a store for $0.89 per tile and rent a tile saw for 40. At another store she can borrow the tile saw for free if she buys tiles there for $1.69 per tile. How many tiles must she buy for the cost to be the same at both stores?

Answer 1

50 tiles.

Explanation:

The difference between the price of the two different tiles is 1.69-0.89=$0.80. Dividing the $40 that the tile saw costs by this difference, you get 50 tiles. PM me if you have more questions! Hope this helps.
