Margo can purchase tile at a store for $0.99 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 $1.39 per tile. How many tiles must she buy for the cost to be the same at both stores?

Answer:

60 tiles

Step-by-step explanation:

Make equations equal,

.99x + 24 = 1.39x

Move all terms containing  x  to the left side of the equation & subtact 24

-.4x = -24

Divide

x = 60

Double check:

.99(60) + 24 = 83.4

1.39(60) = 83.4

i hope this helps :)
