Answer:
$26.98
Step-by-step explanation:
1. You have the following information given in the problem above:
- Lou filled the tank with gas that cost $3.80 per gallon.
- Lou's car had 5.9 gallons in the 13-gallon tank.
2. Therefore, if he filled the tank, you can calculate the total amount of money Lou spent, by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
This is a quadratic equation:
y = a x² + b x + c, a > 0 ( opening upward )
The zeroes are: ( - 1 , 0 ) and ( 4, 0 ).
y = a ( x - x 1 ) ( x - x 2 )
y = a ( x + 1 ) ( x - 4 )
y = a ( x² - 4 x + x - 4 )
y = a ( x² - 3 x - 4 )
