A cell phone company charges $3.00 to make a phone call plus $0.15 for each minute for each minute you talk. Which equation would you use to determine the total cost, c, of a phone call that is m number of minutes long?

• c = 3.00 - 0.15m
• c = 0.15 + 3.00m
• 3.00 = c + 0.15
• c = 3.00 + 0.15m

Julie bought 5 pairs of shoes and 4 blouses. The shoes were priced at $19 per pair and the blouses cost $16.50 each. Which equation can be used to find the total cost, t, she spent on the shoes and blouses?

• 5(16.50) + 4(19) = t
• 5(16.50) - 4(19) = t
• 4(16.50) + 5(19) = t
• 4(16.50) - 5(19) = t
