John's living room is 440.25 ft2. He wants to redo the carpet floor, and make it wooden. It cost \$0.89 cents per square foot. How much money would he need to redo them?

John also wants to paint his house. He asked his threee friends for help.

Friend #1 can paint 75% of his house in 3.25 hours.

Friend #2 can paint 60% of his house in 2.96 hours.

Friend #3 can paint 56% of his house in 2.89 hours.

Who can paint it the fastest?

First one

Cost   = Sq Ft   x Price per Sq Ft  =

440.25 * .89  =

\$391. 82

Second one

Friend #1 can paint 75% of his house in 3.25 hours.

Friend #2 can paint 60% of his house in 2.96 hours.

Friend #3 can paint 56% of his house in 2.89 hours.

To see which can paint the fastest....take the given time and divide by the percent expressed as a decimal...the "least" answer is the fastest

So...we have

3.25 /.75

2.96 / .60

2.89 / .60

Can you finish it, DP????
