Question

Ted Thomason found a good deal when he purchased a bedding set. He paid the store's clerk two $20 bills and a $5 bill. The clerk gave him $2.65 in change. If the sales tax is 7.2%, what was the selling price of the bedding set before taxes?

Answer 1

i guess he paid a total of \(2\times 20+5-2.65=45-2.65=\$42.35\)

Answer 2

to add \(7.2\%\) you multiply a number by \(1.072\) and so you know
\[1.072P=42.35\] making
\[P=42.35\div 1.072\]

Answer 3

So $39.51

Answer 4

or \(\$39.50\) rounding down slightly
either way, you are probably more correct
