Step-by-step explanation:

Given that a person's weekly take-home pay includes a base salary of $379 plus 9% commission on  their weekly sales.

a) Now, if we represent $y as the weekly take-home pay and $x represents the weekly sales, then the equation models the situation will be

y = 379 + 0.09x .......... (1) (Answer)

b) Now, if y = $752.77 (given) then from the equation (1) we get,
