WILL MARK ANSWER FAST. Sarah's car needs repairs. Honest Harry will charge $70 per hour plus $130 for parts. If Sarah's total bill was $410, how many hours did it take
Honest Harry to fix her car? Write an equation to model the problem and
then solve.
a. Equation:
b.

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.
