Nostrana [21]

Answer:

(a) Equation: $T_n = 11.25 - 1.25n$

(b) 7.5 gallons

Step-by-step explanation:

Given

Current Gas = 10 gallon

Every Hour = -1.25 gallon

Solving for (a): An equation for the scenario

This question represents an Arithmetic Progression and will be solved using the following formula:

$T_n = a + (n - 1)d$

Where

$a = 10$

$d = -1.25$

Substitute these values in the formula

$T_n = 10 + (n - 1) * -1.25$

$T_n = 10 -1.25n +1.25$

Collect Like Terms

$T_n = 10 + 1.25 - 1.25n$

$T_n = 11.25 - 1.25n$

Solving for (b): In this case, n - 3

Substitute 3 for n in $T_n = 11.25 - 1.25n$

$T_3 = 11.25 - 1.25 * 3$

$T_3 = 11.25 - 3.75$

$T_3 = 7.5$

7.5 gallon of gas left
