Answer:

21

Step-by-step explanation:

We need to determine the percentage of defects of shoes for brand A

Percentage of shoes that have defect = (5/600) x 100 = 0.83%

shoes that would have defects when 2500 shoes are manufactured = 0.83% x 2500 = 0.0083 x 2500 = 20.75

rounding off to the nearest whole number gives 21 shoes

  • <em>1. Morty's total cost for the items he purchased was </em><u><em>$210</em></u>
  • <em>2. Morty's revenue from the sale of the items was </em><u><em>$547</em></u>
  • <em>3. Morty's Total profit was </em><u><em>$337</em></u>

<em />

Explanation:

The complete question is:

<em>Morty buys and sells computer parts. He bought two monitors for $25 each and later sold them for $88 each. He bought four cases for $15 each and later sold them for $24 each. He bought five memory modules for $20 each and later sold them for $55 each.</em>

<em />

  • <em>Morty's total cost for the items he purchased was</em>
  • <em>Morty's revenue from the sale of the items was</em>
  • <em>Morty's Total profit was </em>

<em />

<h2><em>Solution</em></h2>

<em />

<u><em>1. Morty's total cost for the items he purchased was</em></u>

<em />

Build a table with the number of parts and their costs:

Component         Amout    Unit cost  Total cost

                                               $                 $

Monitors                2             25                50

Cases                     4             15                 60

Memory                  5             20               100

Total cost = $50 + $60 + $100 = $210

<u><em>2. Morty's revenue from the sale of the items was</em></u>

<em />

Build a table with the number of parts and their selling prices:

Component         Amout    Unit price  Total cost

                                               $                 $

Monitors                2              88               176

Cases                     4              24                96

Memory                  5             55              275

Total revenue: $176 + $96 + $275 = $547

<u><em>3. Morty's Total profit was </em></u>

<em />

The total profit is the total revenue less the total cost: $547 - $210 = $337.
