You will receive a 10% discount off your first cell phone bill. Your monthly cell phone plan charges a flat monthly fee of $10.00 plus $0.25 per minute. If you talk on your cell phone for 400 minutes during the first month of cell phone service, what will be the amount of your first cell phone bill?

Answer:$99

Step-by-step explanation:

You receive a 10% discount off your first cell phone bill

Monthly cell phone plan charges a flat monthly fee of $10.00 plus $0.25 per minute

If you talk on your cell phone for 400 minutes during the first month of cell phone service

Total cost on your cell phone for 400 minutes during the first month of cell phone service

= 10 + 400*0.25=$110

Discount off first cell phone bill = 10% of this total cost = 10/100 * 110

=0.1 * 110 = $11

the amount of your first cell phone bill

= total cost - discount

110-11 = $99
