Answer 1

Answer:

Question 1

Cost per 10,000 Popsicle sticks = $725.20

⇒ Single Popsicle stick = 725.20 ÷ 10000 = $0.07 (nearest cent)

Question 2

Cost per 1,000 motherboards = $8,730

⇒ Cost of Single motherboard = 8730 ÷ 1000 = $8.73

Cost per 10 motherboards = $100

⇒ Cost of Single motherboard = 100 ÷ 10 = $10

Difference = 10 - 8.73 = $1.27

Question 3

Create a table with the cost per 1 unit:

$\begin{array}{| c | c | c | c |}\cline{1-4} \sf PART & \sf COST\:PER\:1\:of\:10 & \sf COST\:PER\:1\:of\:1000 & \sf COST\:PER\:1\:of\:10000\\\cline{1-4} \sf Motherboard & \ 10.00 & \ 8.73 & \ 7.04 \\\cline{1-4} \sf Processor & \ 5.00 & \ 1.25 & \ 0.63 \\\cline{1-4} \sf Popsicle & \ 0.10 & \ 0.09 & \ 0.07 \\\cline{1-4} \sf Motor & \ 4.50 & \ 0.18 & \ 0.04 \\\cline{1-4} \sf Sensor & \ 6.30 & \ 4.54 & \ 3.18 \\\cline{1-4} \sf Small\:gear & \ 1.00 & \ 0.80 & \ 0.70 \\\cline{1-4} \end{array}$

From inspection of the table, the Motor saves the most money per unit when 10,000 is bought, since the difference between the cost of 1 unit is the greatest for this part.

Question 4

Cost of 1100 motherboards

= cost of 1000 +  cost of 10 x 10

= 8730 + 100 x 10

= 8730 + 1000

= $9,730

Question 5

Cost of 12050 sensors

= cost of 10000 + cost of 1000 x 2 + cost of 10 x 5

= 31752 + 4536 x 2 + 63 x 5

= 31752 + 9072 + 315

= $41,139
