Answer:
88.99
Step-by-step explanation:
his plan includes 800 minutes for 79.99, all we need to do is calculate the cost of the extra 50mins he used and add it to 79.99. this is ((850-800)*0.18) +79.99 and this is equal to 88.99
$79.99 for the month of 800 minutes
$0.18 X 50 minutes over the included 800
Total = $79.99 + $9 = $88.99
$0.18 X 50 minutes over the included 800
Total = $79.99 + $9 = $88.99
