Question

Issac fills up his 20 -gallon gas tank with fuel that costs $3.54 per gallon. The expression 3.54g represents the cost for a number of gallons of fuel. What does the variable g represent?

Answer 1

g represents the number of gallons

Answer 2

variable g represents the number of gallons

Explanation:

Slope-intercept form:

The equation of the line is:

`y=mx+b`

where, m is the slope and b is the initial value or y-intercept.

Let g represents the number of gallons and c(g) represents the total cost for a number of gallons g.

As per the statement:

Issac fills up his 20 -gallon gas tank with fuel that costs $3.54 per gallon.

⇒C(0)=b= 20 gallons

It is given that:

costs per gallon = $3.54

in g gallons = $ 3.54 g

⇒
`c(g) = 20+3.54g` where, g represents the number of gallons

The expression 3.54 g represents the cost for a number of gallons of fuel.

⇒The variable g represents the number of gallons
