Jane’s cell phone plan is $40 each month plus $0.15 per minute for each minute over 200 minutes of call time. Janes cell phone bill last month was $58.00. What equation can be used to determine the number of minutes over 200 that Jane was billed?

The equation is whose solution is

Step-by-step explanation:

Let us call the number of minutes the phone is used over 200 minutes, then we have

(this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )

This equation can be used to solve for   u as follows:

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 !
