(need ! ) 2. a cell phone provider charges $30 each month to have a cell on their plan, but their talk and text are not free. it costs $0.05 for every minute of talk and $0.10 for every text sent. there is no charge for receiving texts.
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
80 95
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

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

answer: '
