Answer:
Cost of Pizza for 1 inch radius is $0.5.
The Direct variation between cost of pizza and radius in inches of pizza is [tex]C= 0.5r[/tex]
Step-by-step explanation:
Given:
Cost of 6 inch pizza = $3.00
We need to find the direct variation equation to represent cost of pizza with a 1 inch radius.
Let Cost f Pizza be represented by 'C'.
Also radius in inches of pizza be represented by 'r'.
First we will find Cost of pizza for 1 inch radius.
Now 6 inch pizza = $3.00
So 1 inch Pizza = Cost of pizza for 1 inch radius.
By Using Unitary method we get;
Cost of pizza for 1 inch radius = [tex]\frac{3}{6} = \$0.5[/tex]
Cost of Pizza for 1 inch radius is $0.5.
Hence We can say the direct variation would be given as;
[tex]C= 0.5r[/tex]
Hence The Direct variation between cost of pizza and radius in inches of pizza is [tex]C= 0.5r[/tex]
