If whitney bought 3 shirts for 24.99 and sales tax was 7.5% what was the total cost of the purchase including sales tax?

Question

jdoe0001 · Answer

well, 24.99 + tax, tax is 7.5% of 24.99
meaning, 24.99 is the 100%
if 24.99 is the 100%, what's 7.5% of that?
well  $\bf \begin{array}{ccllll}
amount&\%
\\hline\
24.99&100\
x&7.5
\end{array}\implies \cfrac{24.99}{x}=\cfrac{100}{7.5}

i may have misread the question, i assumed that the question had sales take that wasnt included. Jdoe read it as though it was already included. Sorry about that

jdoe0001 · Answer

so the total purchase is 24.99 + 1.87425

The Length of the highway is 700 miles. If 1 inch represents 75 miles, what is the length of the highway on the map? @jdoe0001 can u help me with this one?

yoloshroom · Answer

ll take a look at it :)

yoloshroom · Answer

so first, we would divide 700/75 to find out how many inches long it is.
Mind doing that and telling me what you get?
