Choose the equation that matches the situation.

If one roll of masking tape costs $1.15, how many rolls can Emma buy with $5.75?

• 1.15(5.75) = x

• 5.75x = 1.15

• 1.15x = 5.75

• x = 1.15/ 5.75

Find the Error
What error did the student make when solving the equation:
5x + 6 =  66
5x - 6 = 66 -6
5x = 60
5*5x= 60*5
x = 300

• The student subtracted 6 from both sides instead of adding

• Student multiplied by 5 instead of dividing by 5

• Student got the wrong answer when subtracting 66-6

• The student did not correctly eliminate the variable from one side of the equation
