Estimate how much Ian spend on his transportation costs each month.Round your answer to the nearest whole dollar. Input only the number. Do not input the dollar sign. Example: 371

Answer 1

588

Explanation

Step 1

Let

monthly debt

a) fixed costs

$\begin{gathered} \text{car payment}\rightarrow\text{ \ 309.49} \\ \text{ insurance}\rightarrow172.96 \\ \text{ maintenance}\rightarrow28 \\ \text{total = }510.45\text{ \ per month} \end{gathered}$

b) gas

Let

$\begin{gathered} rate=\frac{3.03\frac{\text{ \ }}{\text{gallon}}\cdot}{33\frac{miles}{\text{gallon}}}=\frac{\text{ \ }}{\text{miles}} \\ rate=0.0918\text{ }\frac{\text{ \ }}{\text{mile}} \end{gathered}$

so, the total cost for the gas is

$\begin{gathered} \text{total cost gas = rate}\cdot average\text{ } \\ \text{total cost gas =842}\frac{miles}{\text{month}}\cdot0.0918\frac{\text{ \ }}{\text{miles}} \\ \text{total cost gas =}77.13\frac{\text{ \ }}{\text{month}} \end{gathered}$

Step 2

finally, the total transpotation costs each month would be

$\begin{gathered} \text{Total = fixed cost+gas} \\ \text{total = \ 510.45+ \ 77.13} \\ \text{total = \ 587.76} \\ \text{rounded ( no dollarsign)} \\ \text{total = 588} \end{gathered}$

therefore, the answer is 588
