Matthew worked 40 hours every week for 8 weeks in a row, earning

a total of $2,880 over the 8-week

period. In this scenario, what is the

constant of proportionality?

A 5

B 9

C 72

D 320

The slope best fit isc. 1/6 mile per hour

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.
