While in Europe, if you drive 117 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite

Hoochie [10]

You would spend $63.58 on gas per week.

Step-by-step explanation:

Given,

Distance per day = 117 km

Distance in a week = 117*7 = 819 km

1 km = 0.6214 mile

819 km = 819*0.6214 = 508.93 miles

Car's mileage = 42.0 mi/gallons

Let,

x be the gallons for 508.93 miles

x gallons = $\frac{508.93}{42}=12.12$

Therefore,

12.12 gallons of gas is needed for one week.

1 US gallon = 3.785 liters

12.12 gallons = 12.12*3.785

12.12 gallons = 45.87 liters

Cost of gas per liter = 1.10 euro

Cost of 45.87 liters = 1.10*45.87 = 50.457 euros

1 euro = $1.26

50.457 euros = 1.26*50.457 = $63.58

You would spend $63.58 on gas per week.

Order the numbers so the steps are accurate. Thanks!

1. Draw a line segment of length s. Label its endpoints PPP and QQQ.
2. Extend the line segment past QQQ.
3. Erect the perpendicular to PQ−→−normal-→PQ {PQ} at QQQ
4. Using the line drawn in the previous step, mark off a line segment of length sss such that one of its endpoints is QQQ. Label the other endpoint as RRR.
5. Draw an arc of the circle with center PPP and radius PQ normal PQ\ {PQ}.
6. Draw an arc of the circle with center RRR and radius QR normal QR\overline{QR} to find the point SSS where itintersects the arc from the previous step such that S≠QSQS\neq Q.
7. Draw the square PQRSPQRSPQRS.

A car is purchased for $28,000. After each year, the resale value decreases by

Dennis_Churaev [7]

$\bf \qquad \textit{Amount for Exponential Decay}\\\\
A=I(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &28000\\
r=rate\to 35\%\to \frac{35}{100}\to &0.35\\
t=\textit{elapsed time}\to &3\\
\end{cases}
\\\\\\
A=28000(1-0.35)^3\implies A=28000(0.65)^3\implies A=7689.5
\\\\\\
\textit{which rounds up to }7689$
