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
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?
