Answer:
The gasoline cost $411.47.
Step-by-step explanation:
This problem can be solved using rules of three.
The first step is finding how many gallons were used.
They travelled a total of 3982 miles. They averaged 24 miles per gallon of gasoline.
So
1 gallon = 24 miles
x gallons - 3982 miles
195.9 gallons were used.
How much did the gasoline cost is the price per gallon was $2.48?
Each gallon costs $2.48. 195.9 gallons were used. So
$2.48*195.9 = $411.47
The gasoline cost $411.47.

Answer:
18.7 years
Step-by-step explanation:
This is a compound interest problem and the following variables have been given;
Principal = 4000; this is the amount o be invested
APR = 9%; this is the compound interest to be earned
Accumulated amount = 20,000
We are required to determine the duration in years. We apply the compound interest formula;
The next step is to introduce natural logarithms in order to determine n;
The number of years required is thus 18.7 years
Answer:
The answer is: y = 3x - 7
Step-by-step explanation:
Given point: (5, 8).
Slope m = 3
Use the point slope form and solve for y:
y - y1 = m(x - x1)
y - 8 = 3(x - 5)
y - 8 = 3x - 15
y = 3x - 15 + 8
y = 3x - 7
Proof:
f(x) = 3x - 7
f(5) = 3(5) - 7
= 15 - 7 = 8, giving (5, 8)
