Answer:

C = 50 + (0.45x)

Step-by-step explanation:

If 500 minutes of talk = 20

and texting = 30

and each additional minute of talk = 0.45

then the bill would be (for C = total cost)

C = 20+30+(0.45 • x)

OR

C = 50 + 0.45x

kipiarov [429]

36 donuts (2 1/2 dozen) = $8.00

So, you divide 8 by 36 and you get about 22¢ for each donut. Then, you do .22 x 12 which equals $2.64.

One dozen donuts = $2.64
