For this case we can make the following rule of three: 2.99 ----------> 100% x --------------> 7% From here, we clear the value of x. We have then: x = ( 7/100 ) ∗ ( 2.99 ) Rewriting the expression we have: [tex]x = (0.07) * (2.99)
x = 0.2093 ** Answer:** ** The sales taxes are:** ** x = 0.2093"> [ / t e x ] < s p an > ∗ ∗ A n s w er : ∗ ∗ ∗ ∗ T h es a l es t a x es a re : ∗ ∗ ∗ ∗ x = 0.2093 **
$0.21. ;
The sales tax on an item that costs $2.99 at a 7% rate is $0.21, making the total cost $3.20. The calculation involves converting the percentage to a decimal and multiplying it by the cost of the item. Finally, you add the sales tax to the original price to find the total amount to be paid.
