Answer:

the cost of one hot chocolate is $2.

Step-by-step explanation:

Let x be the hot chocolate cost and y be the newspaper cost.

Given:

A newspaper and three hot chocolates cost $7

So, the equation is

3x+y=7--------(1)

Two newspapers and two hot chocolates cost $6

So, the second equation is.

2x+2y=6---------(2)

Find one hot chocolate cost?

Solve equation 1 for y.

3x+y=7

y=7-3x

Put y value in equation 2

2x+2(7-3x)=6

2x+14-6x=6

14-4x=6

-4x=6-14

-4x=-8

negative sign is cancelled both side.

x=\frac{8}{4}

x=2

Therefore, the cost of one hot chocolate is $2.

You and your friends go to the movies. The cost of admission is $9.50 per person create a table . Can anyone help me create the
KiRa [710]

Answer:

To create a table like that, you can have two columns. One labeled "Number of People" and the other "Price in Dollars." Since each ticket costs $9.50, the cost for one person must also be $9.50. For two people it would be $19.00 (9.50×2), and so on. The cost of the tickets are proportional to the amount of people. This is because the tickets sell at a constant rate, also know as the constant of proportionality, which in this case is 9.50.

Step-by-step explanation:

<u>Number of people </u>                                         <u>Price In dollars</u>

             1                                                                  9.50

             2                                                                 19.00

             3                                                                28.50

So on.....

I hope this helps you :)
