1) a water park charges $5 for entry into the park and an additional $2 for each of the big waterslides. steven spent $17 on his visit to the water park. which equation can be used to find the number of big waterslides, x, that steven went on?
a.5 + 2x = 17
b.5x + 2 = 17
c. 5x + 2x = 17
d.5 + 2 = 17x

2) the $5 amount is fixed, so there must be a 5 by itslef in the equation.

the amount he paid per waterslide was $2.
he paid for
1 waterslide, 2 * 1
2 waterslides, 2 * 2
3 waterslides, 2 * 3
x waterslides, 2 * x = 2x

now you need to add the fixed cost of 5 to the cost for x waterslides of 2x and make it equal to what he spent, $17.

which equation above shows this?
