A womaan buys three pairs of jeans for $99.84, including sales tax. If each pair of jeans cost $32, what was the sales tax rate?

You can put this solution on YOUR website!
The sticking point ( for me anyway ) is the exact meaning
of " each pair of jeans cost $32 "
That sounds ( to me ) like the cost/jean is without tax.
Based on that,
I can divide $99.84 by 3 and that gives me
( cost of 1 pair of jeans ) + ( tax on 1 pair of jeans )
it tells you that ( cost of 1 pair of jeans ) = $32
So, now I have
+99.84+%2F+3+=+32+%2B+t+ where t is the tax on 1 pair of jeans
They applied the tax, +t+ to $32, so the tax RATE is
+%28t%2F32%29%2A100+ ( to give you a percent )
Does this help?
