Question

The new pane will cost $91.00 plus an additional fee for installation. A local contractor charges $120 per hour for installation. if it only takes 45 minutes to replace the window , what will be the total cost?

Answer 1

120÷4=30. this is the rate per 15 minutes.
30×3=90. this is the rate for 45 minutes.
91+90=181$

Hope this helped:)

Answer 2

the total cost would be $211.
