A jacket that is regularly sold for $49.95 is on sale for 25% off. What is the sale price of the jacket?

What will be the tax if the state has an 8% sales tax?

What is the final cost to you?

First, find 25% of 49.95. Turn 25% into a decimal by dividing by 100.

25% ⇒ 0.25

Now, multiply 0.25 by 49.95.

0.25 × 49.95 = 12.46

25% of 49.95 is 12.46, so subtract 12.46 from 49.95.

49.95 - 12.46 = 37.49

The discounted price of the jacket is $37.49.

Now find 8% of 37.49.

8% ⇒ 0.08

Multiply 0.08 by 37.49.

0.08 × 37.49 = 2.99

The tax is $2.99.

To find the full price, add 37.49 and 2.99 together.

37.49 + 2.99 = 40.48

The final cost is $40.48.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
