Question

For a telephone call from New York City to Los Angeles, a telephone company charges $1.05 for the first three minutes and $0.25 for each additional minute.

Which of the expressions shows the cost of any phone call over 3 minutes? (m  represents the number of minutes over 3)



A) 1.05 + 3m
B) 1.05 + 0.25(3)
C) 1.05 + 0.25m
D) 1.05 - 0.25m
E) 1.05(3) + 0.25m

Answer 1

c because m is the number of minutes over 3 so you would multiply that by 0.25 and add 1.05 altogether.

1.05 is what under 3 minutes is. 0.25 times m(the number of minutes over 3) and add them.

1.05+0.25
