Answer:
minutes at daytime rate: 3.00
minutes at nighttime rate: $2.70
total cost of call: $8.55
Step-by-step explanation:
split up the hours so you have the 5 cent charge per minute for 1 hour and you have the 3 cents a minute for an hour and a half after 8.
multiply 5 cents a minute by 60 to get the amount of money for the first hour($3.00),
next multiply 3cents a minute by an hour and a half (90 minutes) to get $2.70
next add the money together to get $5.70 and multiply that by 1.5 to get $8.55
288. 4 times 3 is 12. Multiply that with 24 and thats your answer.
First you want to subtract 21.91 from 68.77 which will leave you with 46.86 then you divide 46.86 by 1.72 then you get about 27.22 so 27.20 gigs were used
