The equation y=10(1.0605)^x represents the winning prize money, in thousands, for first place in the indianapolis 500 auto race. let x represent the number of years. let x=0 for the year of the race in 1911. find the winning prize money in 1961? (hint: let x = 50 for 1961)

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4
