This is the call plan for minna's cell phone $15 a month plus $0.20 per minute of call time. Minna made 30 minutes of calls this month and 110 texts. How much does she have to pay the phone company?

To solve this you would do the following:

We know her plan is $15/monthly, regardless of any additional texts/calls she makes.

If 1 minute = $.20 worth of money, we would simply multiply 30 (she made 30 minutes worth of calls) x $.20 ($.20 for each minute). The product is $6.

So, $15 + $6 = $21.

Unless the amount owed per text is mentioned and you forgot to include it in the title, you would not need to take this into consideration.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
