Jordan mows lawns to make money. He earns $65 for every lawn, l, that he mows. Last week, he earned a total of $390 mowing lawns.

Part A

What are we solving for?

Part B

Create an equation that represents Jordan's situation.

Multiple Choice

Using our equation $65\ l\ =\ 390$  which operation would we perform on both sides of the equation to isolate and solve for l?

• add 65

• subtract 65

• multiply 65

• divide 65

Multiple Choice

Using our equation $65\ l\ =\ 390$  how many lawns, l, did Jordan mow last week?

• 12 lawns 

• 5 lawns

• 6 lawns

• 10 lawns

Tania is riding a train for 43.6 miles to get to her destination. The train has 14.3 more miles to travel before arriving at Tania's destination.

Which equation and solution correctly represent how many miles, m, the train has already traveled?

• m + 14.3 = 43.6

  m = 29.3

• m + 43.6 = 14.3

  m = 29.3

• m + 14.3 = 43.6

  m = 57.9

• 43.6 + 14.3 = m

  m = 57.9
