jeremiah is tracking how many customers he can assist in an afternoon. he listed the number of customers assisted per hour in the following table:
hour (x) number of customers
f(x)
1 2
2 4
3 6
determine if these data represent a linear function or an exponential function, and give the common difference or ratio.
a. this is an exponential function because there is a common ratio of 2.
b. this is a linear function because there is a common difference of 4.
c. this is an exponential function because there is a common ratio of 4.
d. this is a linear function because there is a common difference of 2.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
