Answer:
Price = $4.50
Maximum revenue = $2,430
Step-by-step explanation:
The concession stand sells 600 bags of peanut at $4.00 (600, $4.00).
If there is a $1 increase in price, the number of bags old will decrease by 120, which mens that 480 bags of peanuts will be sold at $5.00 (480, $5.00).
Tracing a linear relationship between price and quantity sold with the two given points:
The revenue function is given by the price multiplied by the quantity sold:
The value of 'Q' for which the derivate of the revenue function is zero, is the output level for which revenue is maximum:
The total revenue of 540 units at $4.50 per unit is:
Sarahtime (min) {3 } 5 12 17
distance (meters) {75} 125 300 425
Eva time (min) {2} 7 10 20
distance (meters) {52} 182 260 520
Sarah:meters over min =75 over 3 = 25 over 1
25 meters per min
Eva :meters over min= 52 over 2 =26 over 1
26 meters per min
eva is the faster swimming because 26 meters per min is faster then 25 meters per min .
i hope this help
Answer:
b = 7
Step-by-step explanation:
So first I'm going to rewrite the equation to 6(b+3)+8b= 116.
Taking the first part 6(b+3), we see that that is equal to 6 * b + 6 * 3.
So that will be 6b + 18.
Let's bring put it back together. 6b + 18 + 8b = 116. We can now combine the terms since they both have 'b'.
(6b + 8b) + 18 = 116 = 14b + 18 = 116.
Now lets isolate our variable. To do that we need to get rid of our 18 so lets subtract it from both sides.
(116 - 18 = 98)
14b = 98
Now lets divide both sides by 14.
14b/14 = 98/14 = b = 7
b = 7
Answer is D.
Because;
The first equation = the second equation
