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 $8.55
The distance is 3, because 7 - 4 = 3.
First, find the number of quarters that are dated 2005 by multiplying 38*(3/5)
You get 22.8, so you round that to the nearest whole number (23)
Then, since each quarter is worth ($.25) you multiply the number of coins by the worth.
23*.25=$5.75
