Answer: $\$73.43$

Step-by-step explanation:

According to the information provided in the exercise, the prices of each item he wants to purchase in the sporting goods store are:

$Football\ pants=\$21.99\\\\ Football\ pads=\$25.95\\\\Football\ cleats=\$25.49$

Therefore you need to add these prices to solve this exercise. The sum will be the total cost for these three items.

You get that the sum is:

$Total\ cost=\$21.99+\$25.95+\$25.49\\\\Total\ cost=\$73.43$

Then, the three items that Cisco wants to purchase will cost $73.43.

Answer:

1. cost per chair: $86.40

2. selling price per chair: $146.88

Step-by-step explanation:

1. The total cost per chair will be the sum of the cost of materials and the overhead cost (equipment, energy, labor, marketing). The cost of materials is ...

$500/(16 chairs) = $31.25/chair

So, the total cost is ...

cost of each chair = material cost + overhead cost

= $31.25 +55.15

cost of each chair = $86.40

2. We assume the markup is 70% of the cost, so will be ...

0.70 · $86.40 = $60.48

Then the selling price of the chair will be ...

selling price = cost + markup

selling price = $86.40 +60.48

selling price = $146.88
