Mr.jacobs budgeted $1,200 for tiles. His sketch of the floor requires him to use 38 white tile. each white tile cost $12. Write

Arturiano [62]

Given:
Budget for tiles = 1,200
number of white tiles = 38
unit cost of white tiles = 12
budget for brown tiles = x

cost of white tiles = 38 x 12 = 456

The inequality would be:

Cost of brown tiles + cost of white tiles < budget
x + 456 < 1,200

solving the inequality:
x + 456 < 1,200
 - 456 -456
x < 744

Mr. Jacobs can spend up to 744 for the brown tiles.
