At meadowsweet restaurant, kevin bought 2 burgers, 2 cake slices, and 1 soda. the burgers cost $1.75 each, the cake slices cost $1.50 a piece, and the soda cost $1.00. how many quarter dollars should he pay?

He should pay 30 quarters

Step-by-step explanation:

To find the number of quarter dollars he should pay, first calculate out the amount of money this would cost. For this, we can multiply the cost of the item by the number of them that we got and then add them all together.

Burgers

2 * 1.75 = 3.50

Cake

2 * 1.50 = 3.00

Soda

1 * 1.00 = 1.00

Total

3.50 + 3.00 + 1.00 = 7.50

Now to find out how many quarters he should pay, we divide the amount by .25.

7.50/.25 = 30

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
