Write an equation to represent this situation.
Shannon drove 420 miles and used 15 gallons of gasoline. How many miles did Shannon's car travel per gallon of gasoline?
Remember: The variable CANNOT be alone on one side of the equation.
15x = 420
or
420/x = 15

Write an equation to solve this situation.
Kim bought a poster that cost $8.95 and some colored pencils. The total cost was $21.35.
Remember: Your equation CANNOT have the variable by itself on one side of the equal sign.
$8.95 + c = $21.35
or
$21.35 - c = $8.95
