Jane’s mobile phone plan charges $0.05 per minute at daytime rates before 8 p. m. and $0.03 per minute at nighttime rates after 8 p. m. A conference call costs 1.5 times the normal rate. Calculate the cost of a conference call lasting from 7 p. m. to 8:30 p. m. Minutes at daytime rate:
Minutes at nighttime rate:
Total cost:

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

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
