Divide the figure into known figures like rectangle and semi-circle
Calculate the area of the whole figure by adding the area of the separate figures
What am I suppose to do so I can help you?
Let x = number of adult tickets sold
Let x-53 = number of student tickets sold
x + x -53 = 697
2x - 53 = 697.
Add 53 to both sides to get:
2x = 750
Divide both sides by 2 to get:
x = 375
375 adult tickets were sold.
