An article retails for $37.50. the city sales tax is 6%, and the federal excise tax is 8%. how much does the article cost altogether?

Total cost of the article altogether is $42.75 .

Step-by-step explanation:

As given

An article retails for $37.50.

The city sales tax is 6%, and the federal excise tax is 8%.

6% is written in the decimal form

= 0.06

Price of city sales tax = 0.06 × Article cost

                                    = 0.06 × 37.50

                                    = $ 2.25

8% is written in the decimal form

= 0.08

Price of federal excise tax  = 0.08 × Article cost

                                             = 0.08 × 37.50

                                             = $ 3

Thus

Total cost of the article altogether = Article cost + Price of city sales tax + Price of federal excise tax

Putting all the values in the above

                                                         = $ 37.50 + $2.25 + $3

                                                         = $ 42.75

Therefore the total cost of the article altogether is $42.75 .

Angle 8 = 60°

Step-by-step explanation:

See the attached diagram.

The measurement of angle 2 is 60°.

Now, angle 2 = angle 4 as they are equal vertically opposite angles.

Hence, angle 4 = 60°

Now, horizontal lines AB ║ CD and the inclined line is the transverse line.

Hence, angle 4 and angle 8 are corresponding angles.

Therefore, angle 4 = angle 8 = 60° (Answer)
