Answer: B.x(0.75)
Step-by-step explanation:
If the jacket has a cost of [tex]x[/tex], but has [tex]30\%[/tex] off and we have to add the [tex]5\%[/tex] in tax, we can write all in the following expression:
[tex]x-30\% x+5\%x[/tex]
Where:
[tex]x[/tex] is the cost
[tex]30\% x=\frac{30}{100}x=0.3 x[/tex] is the percent off
[tex]5\%x=\frac{5}{100}x=0.05x[/tex] is the tax
Then:
[tex]x-0.3 x+0.05 x=0.75 x[/tex]
This can be also rewritten as:
[tex]x(0.75)[/tex]
Hence, the correct option is B.
