The following data table represents the total cost of a monthly cell phone bill as a function of the number of minutes that the phone is used each month.

minutes 500 750 1,000 1,250 1,500
total monthly cost (in dollars) $62 $77 $92 $107 $122

the table shows that as more minutes are used each month, the total monthly cost will increase at the same rate. assuming that this is true, what is the total monthly cost for the cell phone if it is used for 2,500 minutes?

find the rate of the increase by subtraction:

$77 - $62 = $15

$92 -$77 = $15

for every 250 minutes ( 750 - 500 = 250) the bill increases by $15

2500 minutes - 1500 minutes = 1000 minutes

1000 minutes / 250 minutes = 4

$15 x 4 = $60

the increase from 1500 minutes to 2500 minutes is $60, now add that to the cost for 1500 minutes:

$122 + $60 = $182 total.

step-by-step explanation:

25+6=31

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
