Question

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?

Answer 1

1.) The answer is A. 5+2x = 17. The x in the equation signifies the number of times Steven went to the big slides. The 5 represents the fixed cost of the slide. The total expenditure in the water park is 17 dollars, and the 2 represents the cost of using 1 big slide.

2.) The answer is still letter A. 5 +2x =17.
