Cindy is carpeting a recreation room 24 ft long and 18 ft wide. If the carpeting costs $18 per square yard, what will be the total cost of the carpet?
The interest rate on an auto loan was % last year. This year the interest rate is %. How many percentage points has the interest rate increased?

24 feet x 18 feet = 432 square feet
3 feet = 1 yard
3 feet x 3 feet = 9 square feet
1 yard x 1 yard = 1 square yard
1 square yard = 9 square feet
432 square feet ÷ 1 square yard =
432 square feet ÷ 9 square feet = 48 square yards
48 square yards x $18 per square yard = $864
========================
The second question doesn't seem to make any sense.
========================
You don't have enough information to solve the third problem. You'd need to know how many days he needs to practice. For today, however, he doesn't need to practice any more.

24 feet = 8 yards
18 feet = 6 yards
8 yards *6 yards = 48 square yards
48 square yards * $18/square yard = $846
============
The percentage difference is the number of percentage points

You might want to check the grammer on the third question.
if he practices FOR an hour each day, he's done.

1) 24 ft = 8 yd, 18 ft = 6 yd, total area in sq yd is 8*6 = 48, and 48*18 = $864 (wow!)
2) Not being psychic, I can't guess the % figures in the second problem
3) And I don't understand this one either

First establish the square footage of the carpet.
24ft times 18ft equals 432 square feet
Three feet equals one yard
a square yard: Three times three equals 9 square feet.
since the total carpet is 432 square feet and we know that 9 square feet equals one square yard
432/9 = 48 square yards
Divide 432 by 9 to obtain 48
48 times 18 equals $ 864
The carpet will cost $ 864.00

24 ft = 8 yd
18 ft = 6 yd
Therefore, the carpet measures
8 yd x 6 yd = 48 yd²
Since it costs $18/yd²
48 yd² x ($18/yd²) = $864

Other questions are vague. pls recheck.
