Answer:
The verbal model and an algebraic expression representing Lindsay's total salary for the week is $400 + 0.15 d.
Explanation:
The base salary of Lindsey is, B = $400.
The commission she earns on every sale made by her is, c = $0.15.
It is provided that Lindsey makes d dollars during the week.
The amount d dollars is the total commission earned by Lindsey in a week.
The formula to compute the commission earned will be represented by the expression:
C = c × $d
= 0.15 d
The expression represent Lindsay's total salary for the week is:
Total Salary = Base Salary + Total Commission
= B + C
= $400 + 0.15 d
Thus, the verbal model and an algebraic expression representing Lindsay's total salary for the week is $400 + 0.15 d.
