Given the statement:

At Best Buy they have a 42' TV that sells for $1250 and is on sale for 15% and sales tax is 6.5%.

Determine the final cost.

Solution:

In order to determine the final cost of the TV, we add first the sales tax of 6.5% then subtract the sale percentage by 15%. Hence we must convert first all the percentage into decimals. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.

= 6.5/100

=0.065

=15/100

=0.15

= $1250(0.065)

=$81.25

= $1250 + $81.25

Orignal price with tax. = $1331.25

Now we can compute the sales price by subtracting 15%.

= ($1331.25)(0.15)

=$199.7

=$1331.25 - $199.7

= $1,131.55

Final answer:

= $1,131.55
