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.
Divide the amount she drove by the total amount she needs to drive, them multiply that answer by 100 to make it a percent. This will give you the percentage she drove. To find the percentage she has left,, subtract from 100%.
64 / 160 = 0.4
0.4 * 100 = 40% ( percent she has already driven)
100% - 40% = 60% left.
