The price of an all-access ticket to the fair is $42.99 before tax. Roland bought the all-access ticket for 40% off. He then pai

jenyasd209 [6]

Answer:

See below

Step by step explanation:

Here it is given that , the price of a ticket is $42.99 before tax . And he got a discount of 40% . So the cost after discount will be ,

$\longrightarrow Cost = \$ 42.99 - \$42.99\times \dfrac{40}{100} \\$

Simplify ,

$\longrightarrow Cost = \$ 42.99 - \$17.196 \\$

$\longrightarrow Cost = \$ 25.79$

Again it is given that he paid a tax of 7% on the discounted price . So the tax paid in dollars will be ,

$\longrightarrow Tax = 7\% \ of \ \$25.79\\$

Simplify ,

$\longrightarrow Tax = \dfrac{7}{100}\times \$ 25.79$

$\longrightarrow \underline{\underline{ Tax =\$ 1.80 }}$

Answer of Part A : He paid a sales tax of $1.80 .

Now the total amount paid can be calculated by adding sales tax to the cost after discount .

$\longrightarrow Total\ Amount = \$ 25.79 +\$ 1.80\\$

Add ,

$\longrightarrow \underline{\underline{ Total \ Amount = \$ 27.59}}$

Answer of Part B : The total amount paid by Ronald for ticket is $27.59 .
