At a clothing store, jackets are on sale for 30% off. Sales tax is 5%. Which expression will calculate the total cost of a jacke
VLD [36.1K]

Answer: B.x(0.75)

Step-by-step explanation:

If the jacket has a cost of x, but has 30\% off and we have to add the 5\% in tax, we can write all in the following expression:

x-30\% x+5\%x

Where:

x is the cost

30\% x=\frac{30}{100}x=0.3 x is the percent off

5\%x=\frac{5}{100}x=0.05x is the tax

Then:

x-0.3 x+0.05 x=0.75 x

This can be also rewritten as:

x(0.75)

Hence, the correct option is B.
