The graph shows the number of people at an amusement park at different times, where 0 represents 9:00 A. M. If this trend continues, about how many people will be at the park at 12:00 P. M.?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
