Answer 2

well, we know her total cost is 664, so, that'd be the 100% of her cost
so... lets's pick any.... say hmmm 156 for the food

if we know 664 is 100%, what is 156 ?
well \(\bf \begin{array}{ccllll}
cost&\%
\\\hline\\
664&100\\
156&x
\end{array}\implies \cfrac{664}{156}=\cfrac{100}{x}\impliedby \textit{solve for }x\)

Answer 7

Divide the cost for a hotel (356) over the total cost (664)

i.e. evaluate this `356/664`

What do you get?

Answer 8

I got 0.53614457831

Answer 9

Multiply that result by 100 and you get what?

Answer 10

53.614457831

Answer 11

If we round to 2 decimal places, we get 53.61%

This is just for the hotel

You'll repeat these steps for the other rows to get the other percentages

Answer 12

Tell me what percentage you get for the "food" row

Answer 13

0.23493975903

Answer 14

now multiply that by 100

Answer 15

so you can convert to percent form

Answer 16

23.493975903

Answer 17

which rounds to 23.49%

Answer 18

And then round off your answer to 2 or fewer percentage points. Please understand that it's practically impossible to be as accurate as 23.493975903. In fact, 23 would be a reasonable answer, since 0.49375903 rounds off to 0

Answer 19

your teacher may want more accurate roundings, but I've seen many cases where 2 decimal places is enough.
