There are 4 boys and 12 girls in Mr. Johnson's club.

There are 6 boys in Ms. Greene's club.

to get the number of girls in greene's club we represent it by x

and intrepret it in ratio

4:6 = 12: x

4/6 = 12/x

cross multiply

4x = 6 x12 = 72

x = 72/4 = 18

Grace [21]

Answer:

Option A. c=8.69+0.30t

Step-by-step explanation:

Let

t ------> the number of additional toppings

c ----> the cost of the pizza in dollars

we know that

The linear equation that represent this situation is

c=0.30t+8.69

This is the equation of the line in slope intercept form

where

the slope m is equal to

m=0.30\frac{\$}{topping}

the y-intercept  b is equal to

b=\$8.69 -----> the cost of a pizza without topping
