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

Samuel bought 3 tires for $79.95 each and some rims for $59 each. He spent a total of $534.85. Which equation could be used to find the number of rims, r, Samuel bought?

• 3(79.95) - 59r = 534.85

• 79.95r - 59(3) = 534.85

• 3(79.95) + 59r = 534.85

• 79.95r + 59(3) = 534.85
