Help Please

Okay, so I have been working on this word problem for a while, and since I'm horrible with percent's I can't figure it out. I have most of the problem solved, but I can't figure out the taxes. I already figured out the pack needed. If you an help me that would be great . c:


1. Each pack of tulips costs $5.95 and each pack of geraniums cost $4.95. From the previous problem you know how many of each pack you will need. (3 packs of geraniums, and 8 packs of tulips.) The sales tax is 5%. How much tax will you be paying for all the flowers, to the nearest cent? How much total will you be paying for all flowers, to the nearest cent?

Hard to tell where you are stuck if you do not post your work.

What did you get for the cost of the flowers pre-tax?

Here is how to apply a percent p to a number n.

\(\displaystyle \dfrac{p * n}{100}.\)

So now what is the tax carried out to the last decimal? Just apply the little formula above.

So what answers do you get for your problem?

Whoops, sorry pretax I got $62.45, but I still don't understand ow to apply tax.

\(\displaystyle 3 * 4.95 = 14.85\)
\(\displaystyle 8 * 5.95 = 47.60\)
\(\displaystyle \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 62.45 = sales\ price\) Good so far.

The sales tax is a percentage of the pre-tax sales amount; in this case 5%. So you just use the formula I gave you in my first post.

\(\displaystyle \dfrac{5 * 62.45}{100} = \dfrac{312.25}{100} = 3.1225.\) Simple.

Now round to cents

\(\displaystyle 3.1223 \implies 3.12 = tax\ due.\)

\(\displaystyle 62.45\)
\(\displaystyle \ \ 3.12\)
\(\displaystyle 65.57 = due\ from\ customer\)

No need to fear percents
