What is the total cost mentioned in the word problem?

• $37.50

• $15

• $92.50

• $55

What variable is used to represent the number of hours in the equation?

• H

• X

• N

• T

What is the first step in solving the equation after writing it out?

• Adding 55 to both sides

• Dividing both sides by 15

• Multiplying both sides by 15

• Subtracting 55 from both sides

• 2.5

• 55

• 15

• 37.50

What should you do after finding the numerical answer to the equation?

• Recalculate the equation

• Ask the teacher for confirmation

• Write the answer in words

• Check the answer with a calculator

What is the final interpretation of the answer in the word problem?

• The trip cost is $55

• The cost of repair is $92.50

• The labor cost is $15 per hour

• It takes 2.5 hours to repair the stove
