Jane has a pre-paid cell phone with A Fee and Fee. She can't remember the exact costs, but her plan has a monthly fee and a charge for each minute of calling time. In June she used 220 minutes and the cost was $124.00. In July she used 710 minutes and the cost was $344.50.Express the monthly cost C as a function of x , the number of minutes of calling time she used. If Jane used 764 minutes of calling time in August, how much was her bill?

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

what is the original number? you forgot to add it.
