PW Solving Writing and Rearranging Equations

Pete mows lawns for 15 dollars per hour (h) and then got a $10 tip. Write an equation that represents the relationship between hours mowed and total profit (p).

• 15p + 10 = h

• ph = 25

• 15h +10 = p

• 15 + 10h = p

• p = 25h

Your business made three times as much on the second week as the first week. If you need to pay each of your 3 employees $1000 for that 2 weeks and you want to make $2000 for the two weeks, how much did you need to make in the first week?

Define the variable:

• x: first week

• x: # of hours worked in the first week

• x: $ made in the first week

• x: $ total profit

• x: # of employees

Your business made three times as much on the second week as the first week. If you need to pay each of your 3 employees $1000 for that 2 weeks and you want to make $2000 for the two weeks, how much did you need to make in the first week?

Write an equation that represents the situation.

• x + 3x - 3000 = 2000

• x + 3x - 1000 = 2000

• 3x - 3000 = 2000

• x + 3x - 3000 - 2000
