Carla is an actuary. Her gross pay for the week is $425.88. She is married and claims 2 allowances for herself and her husband. What amount will Carla's employer withhold from her pay for FIT.

The total should be $14.00 but I don’t know how to get there

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.
