Question

At a carnival, single rides cost $2 each, and all day ride passes cost $15. The total revenue for the day was $2,960. Which equation can be used to represent x, the number of single ride passes sold and y, the number of all day ride passes sold?
2x + 15y = 2,960
12x + 5y = 2,960
15x + 2y = 2,960
17x + 15y = 2,960

Answer 1

Answer:

Iwhat sum is this in maths

Answer 2

Let the number of toys/day=x

cost =>(55-x)

x(55-x)=750

55x+x²=750

55x+x²-750=0
