Quesnom 3 Billy gets a job as a salesperson. She is paid 3.5% commission on her first $80,000 in sales and 4.5% commission on any sales above $80,000 and up to $150,000. She earns 5.5% commission on any sales above $150,000. How much money would she earn if she had $273,492 in commissionable sales last month?​

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.

None of them would be estimated to be 3.5.
