per month and 75 paise for each extra minute
she talks over the allowed number of minutes
in the monthly plan. She received a bill of
7 178 last month. How many extra minutes did
sbe use her phone beyond the allowed time.​

Answer 1

Answer:

44 minutes

Step-by-step explanation:

no. of extra minutes be x

amount charged for every extra minute = 75 paise = 0.75rs

total extra amount charged = total no. of extra minutes × amount charged for 1 minute = 0.75x

amount paid last month = 178rs

bill amount (without extra minutes) = 145rs

so,

0.75x + 145 = 178

(solve for x)

0.75x = 178 - 145

0.75x = 33

x = 33/0.75

x = 44

Total no. of extra minutes = 44.
