Tina is charged the following amounts for her cell phone.

· A basic amount of $0.75 per day.

· An additional amount of $0.25 for each text message she sends.

Write an equation to represent y, the total cost in dollars for a day in which Tina sends x text messages.

• y = 0.75x + 0.25

• y = 0.25x + 0.75

• y = 0.25x + 0.25

• y = 0.75x + 0.75

Francis has $120 in savings and makes $10.50 per hour. Margie has $90 in savings and earns $13.75 each hour. What is the logical first step?

• The equation is 13.75x + 120 = 10.50 + 90. The logical first step is to subtract 90 from both sides

• The equation is 13.75x + 120 = 10.50x + 90. The logical first step is to subtract 10.50 from both sides

• The equation is 10.50x + 100 = 13.75x + 90. The logical first step is to add 90 to both sides

• The equation is 10.50x + 100 = 13.75x + 90. The logical first step is to subtract 10.50x from both sides

The water in the canal was 24 meters deep at noon. As the rain came down, the water depth increased at a rate of 0.034 meters per minute. Write an equation which can be used to solve for t, the time in minutes it took the water depth to reach 32 meters.

• $\frac{t}{0.034}-24=32$

• $0.034t+24=32$

• $\frac{t}{0.034}+24=32$

• $0.034t-24=32$
