First, you want to find the area of the entire thing first.

The length adds up to 14, the width to 10. Multiply and you get 140 as the total area.

Now to get rid of the flower bed is simple, 8 Multiply to 3 which makes 24, then divide by 2 which is 12. Substract 12 to 140 and you get 128.

The formula for a trapezoid is Area= (base1 +base2)/2 times height. Following this, and 5 and 7 which gets 12. divide 12 to 2 and you get 6. 6 times 10 is 60.

Subtract 60 to 128 and you get 68.

Mark best if possible please.

A used car dealership initially prices a car at $12,000. When the car fails to sell, the dealership reduces the prices to $10,50

Norma-Jean [14]

Answer:

16.9% to the nearest tenth of a percent

Step-by-step explanation:

First, find the FINAL sale price (after the additional holiday 5% reduction).

If we wish to reduce $10,500 by 5%, that means the final price is 95% of the before price.

95% = 95/100 = 0.95

So 95% of $10,500 = 0.95 x 10500 = $9,975

To find the total percent discount, we use the percent change formula:

percent change = (difference between the values ÷ original amount) x 100

= ((12000 - 9975) ÷ 12000) x 100

= 16.875%

So the total percent discount from the car's initial price to the hoiday sale price is 16.9% to the nearest tenth of a percent.
