Answer:
x = 5
Step-by-step explanation:
The total cost C (in dollars) to participate in a ski club is given by the literal equation :
C=85x+60C=85x+60
Where x is the number of ski trips you take.
1. When C = 315 ;substituting the value of C in the above equation.
315=85x+60315=85x+60
=> 85x=315-6085x=315−60
=> 85x=25585x=255
x = 3 trips.
2. When C = 485
485=85x+60485=85x+60
=> 85x=485-6085x=485−60
=> 85x=42585x=425
x = 5 trips.
Answer:
66.7
Step-by-step explanation:
tan27 = 34/x
0.5095 = 34/x
x = 34/0.5095
= 66.7
$42.08 because 7$ or 3$ is not reasonable because it is 49$ and if it is 15% off it cannot go up to 56$ so it is 42.08 hope this helps can u mark me brainliest
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Using a graphing tool
see the attached figure
This is the equation of a vertical parabola open downward
The vertex is the point (3.25,225) (a maximum)
The zero's of the function or the t-intercepts are the points (-0.5,0) and (7,0)
The h-intercept of the function is the point (0,56)
The domain of the function are all real numbers
The range of the function 
----> All real numbers less than or equal to 225
