Gitta is planning a birthday party.she has an $80 budget. Pizzas cost $5 each,2-liter bottles of soda cost $3 each,and delivery is charged at a flat rate of $5.If she buys 12 pizzas,how many bottles of soda can she buy? how to solve

Answer 1

we are given with the total budget of $80 that is to be divided to pizza, soda, and the service charge. The equation to be followed as a representation to this problem is 80 = 5 + 5x + 3y where x is the number of pizzas and y is the number of bottles bought. if x is 12, then

75 = 60 + 3y
15 = 3y
y = 5 soda bottles
