NOBODY ANSWERING PLS ANSWER
At Best Buy they have a 42” TV that sells for $1,250 and is on sale for 15% off. The sales tax is 6.5%. What is the final cost? (Remember to round to the nearest penny)

First, calculate the discount.

15% of 1250 is 187.5

Then, subtract 187.5 from 1250.

You get 1062.5

Next, to calculate the sales tax. I'm not 100% sure if you're supposed to do this before the discount or after, I'm just assuming after.

Anyway,  

6.5% of 1062.5 is approximately 69.06.

Add that to 1062.5 to get the final answer of $1131.56
