Mel fills his gas tank up with 6 gallons of gas for a ost of $30. How much would it cost to fill an 18 gallon tank?
We can calculate the cost per gallon by dividing the total cost by the number of gallons: $30 ÷ 6 gallons = $<<30/6=5>>5/gallon
To fill an 18-gallon tank, it would cost: $5/gallon × 18 gallons = $<<5*18=90>>90. Answer: \boxed{90}.

Sure! Let's solve the problem step by step.
1. Given information: Mel fills his gas tank up with 6 gallons of gas for a total cost of $30.
2. To find the cost per gallon, we divide the total cost by the number of gallons: $30 ÷ 6 gallons = $5/gallon.
3. Now, we need to calculate the cost to fill an 18-gallon tank. We'll multiply the cost per gallon ($5) by the number of gallons (18): $5/gallon × 18 gallons = $90.
Therefore, it would cost $90 to fill an 18-gallon tank.

Okay! Here's the solution without words:
Given:
Gas tank size: 6 gallons
Cost to fill 6 gallons: $30
To find the cost to fill an 18-gallon tank:
Cost per gallon: $30 ÷ 6 = $5
Cost to fill 18 gallons = $5 × 18 = $90
Therefore, it would cost $90 to fill an 18-gallon tank.
To find out how much it would cost to fill an 18-gallon tank, we can set up a proportion based on the ratio of gallons to cost.
The ratio of gallons to cost remains the same, so we can write:
6 gallons / $30 = 18 gallons / x
To solve for x, we cross-multiply:
6 * x = 18 * $30
Now, we can calculate:
6x = 540
Dividing both sides of the equation by 6:
x = 90
Therefore, it would cost $90 to fill an 18-gallon tank.
To find out how much it would cost to fill an 18-gallon tank, we can use the concept of proportions. Since we know the cost for filling a 6-gallon tank is $30, we can set up a proportion to find the cost for filling an 18-gallon tank.
The proportion can be set up as follows:
6 gallons / $30 = 18 gallons / x
We can cross-multiply and solve for x:
6x = 18 * 30
6x = 540
Now, divide both sides of the equation by 6:
x = 540 / 6
x = 90
Therefore, it would cost $90 to fill an 18-gallon tank.
