x + x + x - 10x = 3x - 10x = - 7x
Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40

T= 54/(150x0.06) =6 years
N= Number of visitors and $P = price $R = Revenue
<span>N = 50,000 - (P-15)*2500 </span>
<span>R = N*P = 50,000P -2,500P^2 + 15*2500P Answer (1) </span>
<span>R = 87,500P -2,500P^2 </span>
<span>dR/dP = 87,500 - 5000P = 0 for max </span>
<span>P = $17.50 for max revenue
