Tom needs carpet for his living room (11x 10 ft) and his bedroom room (20 x 16 ft). At $14.99 per square yard installed or $19.99 per square yard installed. How much would he save by choosing the cheaper carpet?
Answered by Reiny
area = 11*10 + 16*20 or 430 square feet

There are 9 square feet in 1 square yard.

divide by 9, then multiply by each unit cost
subtract the two costs to find the savings.

430 /9= 47.777

47.78*19.99=955.12 less
47.78*14.99 =716.22

Answer $238.90 he would save ... Correct?
Answered by Reiny
yes, arithmetically you are correct,

comment:
What do you think would happen if you went into a store and asked for 47.7777 square yards of carpet?
I wish text-book authors would think before they make up such unrealistic problems.

e.g. most likely you will have to buy a carpet which is 12 ft wide, and have waste.
For the other room you might even have to join different widths.
