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

310 moneys

Step-by-step explanation:

answer:

c

step-by-step explanation:

because i'm smart bruh

answer:

d. 0.06x + 32

step-by-step explanation:

it needs high-low method of cost to determine variable and fixed cost, and then find the cost function.

given,

highest activity = 1500 minutes

lowest activity = 500 minutes

higest cost = $122

lowest cost = $62

we know, variable cost under high-low method = (highest cost - lowest cost) / (highest activitiy - lowest activity)

therefore, variable cost = $(122 - 62)/(1500 - 500) minutes

variable cost = $60/1000 = $0.06

fixed cost = total cost in highest activity - variable cost per minute * highest activity

fixed cost = $122 - ($0.06*1500)

fixed cost = $122 - $90 = $32

therefore, liner cost function = variable cost per minute * fixed cost

y = 0.06x + $32

therefore, d is the answer.

answer:

i'm thinking it is answer c

step-by-step explanation:

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.

from the given data , let us chose any two points to find the slope.

(500, 62) and (750, 77)

the formula to find slope is given by :

plugging the values ,

slope = 15/250

so our slope(m) is 0.)

now we will use point slope form to find the equation:

let us use point (500,62) and slope 0.06 here

now we have to find what is the total monthly cost for the cell phone if it is used for 2,500 minutes.

so plugging x as 2500 in the given equation to find y, we have :

y=182

answer : total monthly cost would be $182 for 2500 minutes.

from the given data , let us chose any two points to find the slope.

(500, 62) and (750, 77)

the formula to find slope is given by :slope = \frac{y2-y2}{x2-x1}  plugging the values slope = \frac{77-62}{750-500} slope = 15/255 so our slope(m) is 0. now we will use point slope form to find the equation: (y-y1) =m(x-x1) let us use point (500,62) and slope 0.06 here (y-62) =0.06(x-50 .y=0.06x +32 now we have to find what is the total monthly cost for the cell phone if it is used for 2,500 minutes. so plugging x as 2500 in the given equation to find y, we have : y=0.06(2500) +32 [/tex] y=182

answer : total monthly cost would be $182 for 2500 minutes.
