What is the answer I am confused on how to do this

You deposit $5000 each year into an account earning 3% interest compounded annually. how much will you have in the account in 30 years?

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.

Select the point that is a solution to the system of inequalities. y< =-x+3 y=x^(2)-3x
