Given the statement:
At an electronics store, a $165 television is marked up 110%. Trevor purchases the TV and must pay 6.5% sales tax.
Determine the total cost of the television.
Solution:
In order to determine the total price, we simply must convert the percentage into decimal. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.
= 110/100
= 1.1
= 6.5/100
= 0.065
Now we need to multiply 1.1 by 165, then add the product to the current price.
= (1.1)($165)
=$181.5
=$181.5 + $165
=$346.5
Now we need to add the sales tax price, by multiplying .065 with 346.5 and add the product to the number again.
= ($346.5)(.065)
= $22.5
= $346.5 + $22.5
=$369
Final answer:
=$369
