Answer:
3x - 2 = 2x + 7
Step-by-step explanation:
Answer:
2x + 18k = X= -9k
Step-by-step explanation:
you have to solve the rational equation by combining expressions and isolating the variable x.
Replace all values of x as 4
f(4)=1/2(4)+5
f(4)=4/2+5
f(4)=2+5
f(4)=7

Answer:
The expectation is 
Step-by-step explanation:
From the question we are told that
The first offer is 
The second offer is 
The third offer is 
The number of tickets is 
The price of each ticket is 
Generally expectation is mathematically represented as

given that they just offer one
Now
given that they just offer one
Now
given that they offer five
Hence the expectation is evaluated as


Now given that the price for a ticket is 
The actual expectation when price of ticket has been removed is


p = number of items sold (note: this is not the profit)
1 item sells for $855, so p items sell for 855p dollars
Subtract off the cost of 6780 and we have the expression 855p-6780 which is the profit for that given month.
Now plug in p = 250 because 250 items were sold in that given month
855*p - 6780 = 855*250 - 6780 = 206,970
The company earns $206,970 in profit for that month. Apply 15% to this value
15% of 206,970 = (15/100)*206,970 = 0.15*206,970 = 31,045.50

Answer: $31,045.50 which is choice C
