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
