The number of apples required to bake a pie varies directly with the square of the diameter of the pie tin. If 4 apples are required for a pie tin with a diameter of 8 inches, how many apples are required for a pie tin with a diameter of 10 inches?

5 apples

Step-by-step explanation:

Solution,

4 apples are required for a pie tin with a diameter of 8 inches

For 1 inch of the pie tin 8/4=2 apples are required.

For 10 inches 10/2=5 apples are required.

Step-by-step explanation:

Let the number of apples be a and diameter be d.

The relationship is:

We have a = 4 when d = 8.

Find k:

The equation is now:

Find a when d = 10:

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
