The cost of a pizza is 30 cents less than 8 times the cost of a soda . If x represents the cost of the soda in terms of cents . Express the cost of the pizza in terms of c . Express in simplest form the cost of 3 pizzas and 5 sodas

Respuesta :

Answer:

c = 8x-30

23x-90

Step-by-step explanation:

Since the cost of soda is x, 8 times the cost of soda is is 8x.

Then, you have to take 30 cents away, so the cost for pizza would be 8x-30 or 8x-.30.

This is your pizza or c.

Next, to put in 3 pizzas and 5 sodas, you just multiply 3 and 5 by the corresponding variables.

So 3(8x-30) + 5(x) = 18x - 90 + 5x = 23x - 90 or 23x - .90
