Question

Jordan bought a notebook for $5, 6 pencils for $1 each, and a binder for $9. The sales tax for the whole purchase was $2

What percent was the sales tax?

Answer 1

10%
If you add it all together it's 20$ +2$ tax so you do this
100% divided by 20$ is equal to x% divided by 22$
100/20=5
5*22=110
110-100=10%
