The price of a box of 15 cloud markers is $12.70. the price of a box of 42 cloud markers is $31.60. all prices are without tax, and the price of the packaging is the same for any size. how much would 50 cloud markers in a box cost? write an equation which will tell the price p for the number n markers in the box.

Here, The price of one box having N markers = Price of N markers + packaging charge

Let M be the price of one Marker and P' be the price of packaging of one box which is same for any size.

Since, The price of a box of 15 cloud markers is $12.70.

That is , 15 M + P' = 12.70 (1)

Also,  The price of a box of 42 cloud markers is $31.60,

That is, 42 M + P' = 31.60 (2),

Equation (2) - Equation (1),

27 M = 18.90,

⇒ M = 0.7

By putting the value of P in equation (1),

We get,

10.5 + P' = 12.70 ⇒ P' = 2.2,

Thus, the price of one marker, M = 0.7

And, the price of packaging one box, P' = 2.2

Thus, the price of a box of 50 marker = 50 × M + P' = 50×0.7 + 2.2 = 35 + 2.2 = $ 37.2

And, the equation that shows the price(P) of a box of N markers,

P = 0.7 N + 2.2

Cost of 50 markers is $37.2

               Equation is

                  P = 0.7N+2.2

Step-by-step explanation:

Let the cost Packaging be 'c'  and x be the cost of one marker and P be the total cost

So the equation for the  total cost is

                        P = Nx +c

then cost of 15 markers is 15x +c = $12.70 equation (1)

similarly cost of 42 markers is 42N+c =$ 31.60 equation (2)

         Subtracting equation 2 from equation 1 ,we get

42N+c = 31.60

-15x -c = 12.70

27x =18.9

x = 0.7

Plugging x = 0.7 in equation 1

15(0.7) + c = 12.7

10.5 +c = 12.7

  c = 2.2

Therefore cost equation is

P = 0.7N +2.2

Cost of 50 markers will be

P = 0.7(50) +2.2

  = 35.0 + 2.2

 =$ 37.2

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
