Answer:
F(x) = 3
Step-by-step explanation:
Just substitute x with 1 and you add it with 2 and your answer is three
Answer:
Rita paid 47,500 dollars for the purchase price.
Step-by-step explanation:
We are given the sales tax on a new car is directly proportional to the purchase price of the car which means there is is something k such that
when you multiply it to the sales tax you get the purchase price.
Let's set this equation:
y=kx
Let y represent the purchase price and x the sales tax.
The second sentence tells us that (x,y)=(1500,30000).
We can plug this into y=kx to find the constant k. (Constant means it stays the same no matter what the input and output is).
So we have:
30000=k(1500)
300 =k(15) I went ahead and divided previous equation by 100.
Now divide both sides by 15:
300/15=k
Simplify:
20=k
So the equation to use the answer the question is
y=20x
where y is purchase price and x is sales tax.
So we want to know the purchase price on a car if the sales tax is 2375.
So replace x with 2375:
y=20(2375)
y=47500
$570.60 because 90/100=.90 so multiply that with 634 with .90 you get 570.60
85 = 10x+15
70 = 10x
x = 7
180-85 = 95 = z
Make an equation.
.1 X .5 X n = .25 X n - 30
.05n = .25n - 30
30 = .20n
150 = n
