A store bought a tent for $230 andmarked it up 65%. The store sells thetent with an 8% tax, what is the totalcost of the tent?
Len [333]

The cost for buying the tent is $230.

65% was increasesd for selling. Then the rate is

\begin{gathered} 230\times\frac{65}{100}=14.95 \\ So,\text{ the marked price=230+14.95=}244.95 \end{gathered}

The tax is 8%. So this is from the marked price.

\begin{gathered} \frac{8}{100}\times244.95=19.56 \\ 244.95-19.56=225.39 \end{gathered}

Therefore the total cost of the tent is $225.39.
