Hi there!

$\large\boxed{-n^2 + 4n}$

Begin by evaluating f - g:

4n - 5 - (n² - 5)

Simplify:

4n - 5 - n² + 5 = 4n - n²

Or it can be written as -n² + 4n to match the first answer choice.

A chili recipe calls for 2 pounds of ground pork and 3.5 pounds of ground beef. The cost of ground beef per pound is $0.20 less

dmitriy555 [2]

Answer: $\$1.75\ \text{per pound}$

Step-by-step explanation:

Given

The recipe calls for 2 Pounds of ground pork and 3.5 pounds of ground beef

Suppose x is the cost of ground pork

So, the cost of ground beef is $2x-0.2$

The total cost of meat is $\$15.05$

The total cost can also be written as

$\Rightarrow 2\times x+3.5\times (2x-0.2)=15.05\\\Rightarrow 2x+7x-0.7=15.05\\\Rightarrow 9x=15.75\\\Rightarrow x=\frac{15.75}{9}=\$1.75\ \text{per pound}$

So, the cost of ground pork is $\$1.75\ \text{per pound}$

The formula is
A=p (1+r)^t
A future value?
P present value 4000
R interest rate 0.06
T time 7 years
A=4,000×(1+0.06)^(7)
A=6,014.52

Interest earned=A-p
6,014.52−4,000=2,014.52
