Amy is putting a new floor in her bathroom. she created a scale drawing of her bathroom floor using a scale of 1/2 inch = 1 foot. in the drawing, the bathroom measures 3 inches by 3 1/2 inches. amy is purchasing square tiles that measure
1/2 foot on each side. the cost of each tile is $3.00. how much will amy pay for the tiles for her bathroom floor?

$78.00

Step-by-step explanation:

First, you would have to figure out how many tiles she would need. 3 inches is  equal to 6 feet according to the scale part, and then it would be 12 tiles because it is half a foot for the tiles. Then 3 1/2 would be 7 feet, and then 14 tiles. 12 plus 14 equals 26, and 26 times $3.00 is $78.00
