A group of friends wants to go to the amusement park. They have $80 to spend on parking and admission. Parking is $5, and tickets cost $18.75 per person, including tax. Write and solve an equation which can be used to determine xx, the number of people who can go to the amusement park.

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
