Answer:
.03472
Step-by-step explanation:
take sell price $20. subtract cost of 11.32 which equals 8.68. then divide 8.68 by the sell price $20
The formula for contribution margin is the sales price of a product minus its variable costs. In other words, calculating the contribution margin determines the sales amount left over after adjusting for the variable costs of selling additional products.

Answer:
The average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).
Step-by-step explanation:
The service rate was given as $11, $84, $94 and $103.
The average service rate = 
= 
= 
= 73
Their average service rate is $73.
But comparing the average service rate to their given service rates, the average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).
Answer:
The inequality is 0.6x < 12.5
The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days
Step-by-step explanation:
14 gallons-1.5 gallons=12.5 gallons
we know that
If the remaining fuel is greater than 1.5 gallons Diego's father can drive the car without the warning light coming on
so
Let
x ----> the number of days
0.6x < 12.5 inequality that represent the situation
Solve for x
x < 12.5/0.6
x < 20.8 days
The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days
Answer: 335ft
Step-by-step explanation:
The tangent of the angle of elevation is the ratio of the dam height h to the horizontal distance downriver of the observer. This gives us two equations for the height:
h= atan(1.1) = (155+a) tan(0.8)
⟹a= h/tan(1.3), 155+a= h/tan(0.8).
Subtracting the first equation from the second,
155=(155+a)−a =h/tan(0.8)−h/tan(1.1)
=h(1/tan(0.8)−1/tan(1.1)).
Solving for h,
h=155 ft (1tan(0.8)−1tan(1.1))−1
155(0.9713 - 0.5090)^-1
155(2.1631) ≈335 ft .
