• large = 20

A football team scored a total of 80 points in one game.  They scored 24 times.  The scoring was made up of touchdowns (6 points), PATs (1 point), and field goals (3 points).  They had three more touchdowns than field goals.  If x represents touchdowns, y represents points after touchdowns (PATs), and z represents field goals, write an equation that represents the total points scored?

Amy wants to buy soda AND pizza for her Halloween party. She has $45 to spend. One case of soda costs $4, and one pizza costs $8. Write an equation that could be used to find a valid combination for as many cases of soda, x, and pizzas, y, as she can afford.

• 8x + 4y = 45

• 4x - 8y = 45

• 12xy = 45

• 4x + 8y = 45

Devon owns a house-cleaning company that has to give price quotes to potential clients. He figures out his price by assuming a $25.00 base charge and then adding 18.00 for each bathroom and $14.00 for every other room. If he uses P for price, B for Bath, and R for other Rooms, which formula represents the price quote formula?

• $P=18B+14R$

• $P=18B+14R\ -25$

• $P=18B+14R+25$

• $P=32BR\ +25$
