Question

Maria has purchased a basic stained glass kit for $100. She plans to make stained glass suncatchers and

sell them. She estimates that the materials for making each suncatcher will cost $13. Model this situation
with a rational function that gives the average cost of a stained glass suncatcher when the cost of the kit
is included in the calculation. Use the graph of the function to determine the minimum number of
suncatchers that brings the average cost below $22.50.
The minimum number of suncatchers that brings the average cost below
$22.50 is

Answer 1

Y’all the correct answer is 10

Answer 2

Explanation:

fixed cost = 100

variable cost = 13

soooo....

cost = (13x + 100)/x

the questions wants to know when cost < 22.50

22.5 > (13x+100)/x

look at graph attached ;)

it looks to me like it's at 11

22.5 > (13(11) + 100) / 11

22.5 > 22.09

try 10

22.5 > (13(10) +100)/10

22.5 > 23 not true so yes.. 11 is when the cost goes below 22.50
