The labor fee is $13.55 and each quart of oil is $2.25
Step-by-step explanation:
Let,
x be the amount of each quart of oil
y be the amount of labor fee
According to given statement;
5x+y=24.80 Eqn 1
7x+y=29.30 Eqn 2
Subtracting Eqn 1 from Eqn 2
Dividing both sides by 2
Putting x=2.25 in Eqn 1
The labor fee is $13.55 and each quart of oil is $2.25

Answer:
205/6
Step-by-step explanation:
The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.
45=-6/5x+86
-41=-6/5x (subtract 86 from both sides)
-41*(-5)=-6/5x*(-5) (multiply both sides by -5)
205=6x (divide both sides by 6)
205/6=x
Mid point elasticity formula
[change in price] / [average price] ÷ [change in quantity] / [average quantity]
change in price = $6 - $4 = $2
average price = [$ 6 +$4] / $2 = 10/ 2 = 5
[change in price] / [average price] = 2/5
change in quantity = 1000 boxes - 600 boxes = 400 boxes
average quantity = [1000 boxes + 600 boxes] / 2 = 1600 boxes / 2 = 800
boxes
change in quantity / average quantity = 400/800 = 1/2
midpoint elasticity = 2/5 ÷ 1/2 = 4/5 = 0.8
0.8 < 1 => inelastic demand (the change is demand is less than proportional to the change in price)
Answer:
-12x-15-8x=85 (first combine like terms)
-20x-15=85 (now add 15 to 85, to get x by itself)
-20x=100 (now divide 100 by negative 20)
x=-5
