Answer:

d = 55 boxes of deluxe

s = 135 - 55 = 80 boxes of standard

Step-by-step explanation:

This is a system of equations.

Let  s = number of standard boxes

     d = number of deluxe boxes

s + d = 135  sold

7s + 13d  = $1275

we can use substitution

s = 135 - d

7*(135 - d) + 13 d  = 1275

945 - 7d + 13d = 1275

6d = 330

d = 55 boxes of deluxe

s = 135 - 55 = 80 boxes of standard

Answer:

  • Architect - $83000
  • Lawyer - $128000

Step-by-step explanation:

  • Salary of a lawyer = l
  • Salary of an architect = a

<u>According to the question we have:</u>

  • l = 2a - 38000
  • l + a = 211000

<u>Substitute l into the second equation and solve for a:</u>

  • 2a - 38000 + a = 211000
  • 3a = 211000 + 38000
  • 3a = 249000
  • a = 249000/3
  • a = 83000

<u>Find the value of l:</u>

  • l = 211000 - 83000
  • l = 128000
