We are given the
perimeter of isosceles trapezoid = 28 in
ratio of length of bases = 5:3
We are to find the lengths of sides of the trapezoid and the diagonal that bisects the angle at the base with a longer length
The formula for the perimeter of an isosceles trapezoid is
P = (1/2) (b1 + b2) h
We are given the ratio
b2/ b1 = 5 /3
b2 = 5/3 b1
Substituting
28 = (1/2) (5/3 b1) h
The height of the trapezoid is expressed in terms of b1
For the diagonal
d² = h² + [(b2 - b1) + (b2 - b1)/2]²
Express h and b2 in terms of b1 and diagonal can be expressed in terms of b1

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