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 ,
[tex]\longrightarrow Cost = \$ 42.99 - \$42.99\times \dfrac{40}{100} \\[/tex]
Simplify ,
[tex]\longrightarrow Cost = \$ 42.99 - \$17.196 \\[/tex]
[tex]\longrightarrow Cost = \$ 25.79 [/tex]
Again it is given that he paid a tax of 7% on the discounted price . So the tax paid in dollars will be ,
[tex]\longrightarrow Tax = 7\% \ of \ \$25.79\\ [/tex]
Simplify ,
[tex]\longrightarrow Tax = \dfrac{7}{100}\times \$ 25.79 [/tex]
[tex]\longrightarrow \underline{\underline{ Tax =\$ 1.80 }} [/tex]
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 .
[tex]\longrightarrow Total\ Amount = \$ 25.79 +\$ 1.80\\ [/tex]
Add ,
[tex]\longrightarrow \underline{\underline{ Total \ Amount = \$ 27.59}} [/tex]
Answer of Part B : The total amount paid by Ronald for ticket is $27.59 .
