Answer:
I believe its B, But I am unsure since I haven't done geometry in a couple years.
Answer:
x = 14
m∠A = 38°
m∠C = 71°
m∠D = 71°
Step-by-step explanation:
Selling Price = $820
Mark up = 25% Cost Price
Selling Price = Cost Price + 25% Cost Price.
Let the cost price = x
Selling Price = x + 25% of x
820 = x + 0.25x
820 = 1.25x
820/1.25 = x
656 = x
Dealer's Cost of refrigeratior = $656
A=a+b+c+d/4
subtract a from both sides
0=b+c+d/4
Subtract b from both sides
-b=c+d/4
Finally subtract d/4 from both sides
c=-d/4-b
The answer to this is B (8%) I found that by working through all the answer options. Hope this helps
