Answer:
a. 61.25
b. 70
c. 212
Step-by-step explanation:
a. What is your cost if you travel 57 miles?
The cost is $ .
y=47+0.25x
y=47+0.25(57)
y=47+14.25
answer: 61.25
b. If your cost was $64.50, how many miles were you charged for traveling?
You were charged for traveling miles.
64.50-47=0.25x
17.50=1/4x
17.50*4
answer 70=x
c. Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?
The maximum number of miles you could travel is miles.
100-47
53=1/4x
answer : x= 212
Answer:
0.0625
Step-by-step explanation:
11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
Answer:
price = $25
maximum profit is $2400
Step-by-step explanation:
Given the function modeled by the community theatre as
p(d)=−4d^2+200d−100
The maximum profit will be ,ade at dP/dd = 0
dP/dd = -8d + 200
0 = -8d + 200
8d = 200
d = 200/8
d = 25
hence he theatre will make maximum profit at a price of $25
Substitute d = 25 to get the maximum profit
p(25)=−4(25)^2+200(25)−100
p(25) = -2500+5000-100
p(25) = 2400
Hence the maximum profit is $2400
The last step in a proof contains the conclusion.
hope this helps:)
