Jen charges $7.50 for every hour, h, she babysits. Write a function, f(h), to represent the total amount Jen would make babysitting h, hours.

f(h) = 1h + 7.5

y = 7.5x

f(h) = 7.5h

y = 8h + 7.5

Mr. Cook is saving money in an account. At the beginning of the year, he has $56 in savings and puts in another $4 per week. Write a function f(x) that models the total amount in the savings account after x, weeks.

f(x) = 56 + 4x

f(x) = 56x + 4

y = 4x + 56

y = -56 - 4x

Water is filling up a bathtub. After the first minute, there are 6 gallons in the tub and then after 2 minutes, there are 11 gallons. Write a linear equation, b(t) to represent the number of gallons in the tub after t, minutes.

b(t) = 11t + 6

b(t) = 6t + 11

b(t) = 1t + 5

b(t) = 5t + 1

Mr. Keefe is walking away from a light pole at a rate of 4 feet per second. If Mr. Keefe starts at a distance of 6 feet from the light pole, write an equation to represent the total distance, D(s) he is away from the light pole after, s, seconds.

D(s) = 4s + 6

D(s) = -4s + 6

y = 4x + 6

y = -6s + 4

The temperature outside is currently 68°F and falling at a steady rate of 4 degrees every hour. Write a linear equation that relates the Fahrenheit temperature, F, to the time in hours, t, it has been falling.

F = -4x + 68

F(t) = -4t + 68

F(t) = 4t + 68

F(t) = 4x + 64

Kyle is starting an exercise program. The FIRST day he will spend 28 minutes on a treadmill. He will increase his time on the treadmill by 4 minutes each day. Write an equation for T(d), the time, in minutes, on the treadmill on day d.

T(d) = 4d + 28

T(d) = 4d + 24

y = 28d + 4

y = 24d + 4
