The greatest common factor is 8
Given
consider substituting 
to get a proper quadratic equation,
Solve for 
; we can factorize to get
Solve for 
:
The first equation has no real solution, since 
for all non-zero . Proceeding with the second equation, we get
If we want to find all complex solutions, we take 
so that the first equation above would have led us to
Answer:
At the restaurant you only have $30 to spend on dinner.
=> 8% sales tax is applied in your bill.
=> And need to leave a 20% tip.
Now, let’s find out how much will be the most expensive item you can order
Let us solve for the 8% tax first
=> 30 dollars * 8%
=> 30 dollars *.08 = 2.4 dollars
Then let’s solve the 20% tip
=> 30 dollars * .20 = 6 dollars
Solve
=> 2.4 + 6.00 = 8.4 dollars
=> 30 dollars – 8.4 dollars = 21.6 dollars
Thus, you can only spend around 22 dollars to be able not to exceed at your 30 dollars budget.
Answer: B
Step-by-step explanation:
1. 50000+1700+2200 = 55300
2. To find 80% trade in free, all we have to do is figure out 80% of 5000 (because thats the cost of his original car) which is 4000. (5000/100 x 80 = 4000)
3. Then you want to subtract 55300 - 4000 because hes trading in the car which means to subtract from the price.
4. Lastly there is a 1200$ destination fee, so you add on 51300+1200 which equals to 52500
A)
C= 200+10N
10 X 50=500
C=200+500=700

Duncan may have rounded up for both, giving hims higher estimate.
