Bill bought a new cellular phone. his monthly bill will be $32.99 each month which includes 100 minutes of use. additional minutes will cost $0.19 per minute. write a linear model that represents the amount of the bill, c, based on the total number of minutes, m, the phone is used in a month. assume m > 100 minutes.
a. c= 0.19m+32.99
b. c= 32.99(m-100)+0.19
c. c= 0.19m
d. 0.19(m-100)+32.99

The correct option is : d.

Step-by-step explanation:

Let the total number of minutes used be = m

Let the amount of bill be represented by = C

As given, the monthly bill will be = $32.99

Assume m > 100 minutes.

Additional minutes will cost $0.19 per minute.

Its given that bill includes 100 minutes of use.

So, above 100 minutes, it will be chargeable at 0.19 dollars per minute. We can represent this as :

And as $32.99 is the bill that has to come each month, the final equation becomes :

57 732

i dont really.know

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
