a. write an algebraic expression that represents the monthly costs of the plan, given t represents the number of minutes and x represents the number of texts sent for each month. b. how much would the plan cost for each of the scenarios below? talk (mins) texts sent total cost
100 50
124 26
75 75

50 100

A cell phone provider charges $30 each month.

It costs $0.05 for every minute of talk and $0.10 for every text sent. There is no charge for receiving texts.

Part A:

Let t represents the number of minutes and x represents the number of texts sent for each month. Let T represent total cost.

Equation becomes:

Part B:

Talk (mins)(t)     Texts(x)

100                    50

124                    26

75                      75

80                     95

50                    100

When t = 100 , x = 50

T = $40

When t = 124 , x = 26

T = $38.80

When t = 75 , x = 75

T = $41.25

When t = 80 , x = 95

T = $43.50

When t = 50 , x = 100

T = $42.50
