answer:
$0.75
Step-by-step explanation:
the function can be represented as:
f(x)=0.25x+3.5
the function produces the following values for years 1, 2, and 3 respectively:
f(1)=0.25(1)+3.5=3.75
f(2)=0.25(2)+3.5=4.00
f(3)=0.25(3)+3.5=4.25
therefore,
there is a $0.75 increase per year

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.
