190 *.80 *(1.05)

Instead of adding the sales tax, he subtracted the sales tax.

159.60

Step-by-step explanation:

If Joel gets 20% off, he still has to pay (100-20) or 80%

The cost of the tablet is now 190 * .80

Then he has to pay 5% sales tax.

The tax is the prices times 5%   plus the original price

190 *.80 *(1+.05)

or 190 *.80 *(1.05)

Instead of adding the sales tax, he subtracted the sales tax.

The total he needs to pay is

190 *.80 *(1.05)

159.60
