<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of dimes and y represent the number of quarters.
A dime is worth 10 cents. A quarter is worth 25 cents.
Hence:
x + y = 17 (1)
Also:
10x + 25y = 290 (2)
From equation 1 and 2:
x = 9, y = 8

Answer:
You can buy 12 gallons of gas.
Step-by-step explanation:
I took 40 and 3.25, then divided them.
I got a very large ugly decimal. When simplified it is 12.
x is the number od doubling periods ( which is given as every 7 years)
28 years / 7 = 4 doubling periods in 28 years
so x = 4
so you now have:
f(x) = 8000 * 2^4
2^4 = 16
so 8000 * 16 = $128,000 would be the answer
