Question from Adalyn, a student:

Hello i've been having some trouble with math, The question is asking for a GST and a PST of a 30.00 dollar shirt. I don't know how to find the GST or the PST please help

Hi Adalyn,

I am a little confused by your question as you didn't give us the PST or GST tax rate. You indicated that you live in Ontario where there is no PST or GST but instead a Harmonized Sales Tax (HST) of 13%. If you bought a $\$30$ shirt in Ontario the tax will be

\[\frac{13}{100} \times \$30 = 0.13 \times \$30 = \$3.90\]

I hope this helps,
