Answer:

he awnser is c) 22d + 12, Every time 1 day of rental is added , the cost rises $22 which means each day you rent the tractor it will be $22 + the fixed fee ( that you can discover by applying d(22) in one of the equations.

Answer:

c = 22d + 12

Step-by-step explanation:

The given table is

Days      Cost to Rent a Truck

   1                        34

   2                       56

   3                       78

   4                       100

To right a function of this expression, we first have to find the ratio of these values and then use the point-slope form to get the equation which is linear, because the table is showing a linear relation.

\(m=\frac{100-34}{4-1}=\frac{66}{3}=22\)

Now, we take one point and the slope to find the linear function

\(y-y_{1}=m(x-x_{1})\\y-100=22(x-4)\\y=22x-88+100\\y=22x+12\)

Therefore, the function has to have a ratio of change of 22 and an y-axis interception at y=12. So, the answer is the first choice, where x is d and y is c.
