<h2>Answer</h2>
f(x) = 190(1.15)x
<h2>Explanation</h2>
To solve this, we are going to use the standard exponential function:
Where
is the final price after 
years
is the initial price
is the rate in decimal form
is the time in years
We know from our problem that the initial price is $190, so 
. Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so 
. Let's replace the values:
Answer:
2/3 gallons
Step-by-step explanation:
Given data
We have the following data
1/2 gallons is the same as 0.5 gallons
hence 0.5 gallons will cover 3/4 of his deck
x gallons will cover 1 of his deck
cross multiply we have
3/4*x = 0.5*1 gallons
3x/4= 0.5
3x= 2
divide both sides by 3
x= 2/3
Hence 2/3 gallons will cover the entire deck
Answer:
x=7
Step-by-step explanation:
5x%2B7=6x Start with the given equation.
5x=6x-7 Subtract 7 from both sides.
5x-6x=-7 Subtract 6x from both sides.
-x=-7 Combine like terms on the left side.
Divide both sides by -1 to isolate x.
x=7 Reduce.
