Answer: B. 130% increase
Step-by-step explanation:
Given function : 
If x represents the number of years, we have to determine the two values of y in consecutive terms to determine if the value of y increases or decreases after a year.
This function is equivalent to the exponential growth function
, where A=0.35 and (1+r)=2.3, [A= initial amount , r=annual percent increase]
Thus,
Hence, the annual percent increase is 130%.
Answer:
x = 4
Step-by-step explanation:
WX = WY
9x - 11 = 7x - 3..........Then subtract 7x to the other side such that
2x - 11 = -3..........Then add 11 to both sides such that
2x = 8...........Then divide 2 such that
x = 4

Answer:
The profit function is p(x)=700x-1150.
Step-by-step explanation:
The monthly expenses, in dollars, for x months of operation is given by the function
The monthly revenue, in dollars, earned by the bakery is given by the function
The formula for profit:
Subtract the revenue and cost function to find the profit function.
On combining like terms we get
Therefore the profit function is p(x)=700x-1150.
