Brian and Amy invest $2700 to start a hair cutting business. Each hair cut costs them $1.50 (supplies). They charge their customer $15 for each cut.

Write the equation for cost and income.

• Cost: y = 1.50x + 2700

  Income: y = 15x

• Cost: y = 150 + 2700

  Income: y = 1.50x

• Cost: y = 1.50x + 2700

  Income: y = 15

• Cost: y = 2700

  Income: y = 15x + 1.50

At a local ballpark a team charges $10 per ticket. The team must pay its players $4000. It costs the owners $6 for each souvenir they give away.

Write an equation for cost and income.

• cost: y = 6x + 4000

  income: y = 10x

• cost: y = 10x + 4000

  income: y = 6x

• cost: y = 10x + 4000

  income: y = 6

• cost: y = 4000x + 10

  income: y = 6x
