Answer:
225 sq. Ft
Step-by-step explanation:
Key words in the question;
Dilated - This means increased pr expanded
Scale factor of 3 - This basically means multiplied by 3
Old square = 75 sq. Ft
This means;
New are = Old area * 3
New area = 75 * 3 = 225 sq. Ft
The regular price is 3.18.
50% off half the price, so you can either divide the regular price by 2 or multiply it by 0.50
3.18 / 2 = 1.59 ( 3.18 *0.50 = 1.59)
so the sale price is 1.59
now subtract the sale price from $5 to find the amount of change they got back:
5.00 - 1.59 = $3.14 change back
