Drew bought golf clubs for $499. They were on sale for 15% off and the tax was 6.5%. What was the total price? (find discount first, then the tax)

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
