Answer: 31500 to 38500

Step-by-step explanation:

Lets find lower limit of guess

35000 - ( 35000 * 10% )

Upper limit of guess

35000 + ( 35000 * 10% )

= 38500

There are 6 gallons in a tank that is 20% full. How many gallons are in a full tank? Use a double number line to show your work.
Alex17521 [72]

Answer: 30 gallons

Step-by-step explanation:

Let the number of gallons that are in a full tank be represented by x.

Since there are 6 gallons in a tank that is 20% full, this will be set up in an equation as:

20% × x = 6

20/100 × x = 6

0.2 × x = 6

0.2x = 6

x = 6/0.2

x = 30

There are 30 gallons in a full tank
