Break it into 2 shapes.

A rectangle: 8 x 7 = 56 square inches.

A triangle: 1/2 x 3 x 4 = 6 square inches.


Total: 56 + 6 = 62 square inches.

Answer:

62 in^2

Step-by-step explanation:

We have a rectangle and a triangle.  We can add these shapes together.

The area of the rectangle is length times width

A = 8*7

A rectangle = 56

The area of the triangle is

A = 1/2 *b*h

The base is 7-4 = 3

The height = 12-8 = 4

A = 1/2 * 3*4 = 6

Adding the areas together

A = 56 + 6 = 62 in^2

Chan receives a bonus from his job. He pays 30% in taxes, gives 30% to charity, and uses another 15% to pay off an old debt. He
charle [14.2K]

Answer:

Chan's Bonus amount was $2400.

Step-by-step explanation:

Let the Total amount receive from bonus be 'x'.

Given:

Chan pays 30% in taxes;

So we can say;

Amount paid in taxes will be equal to 30% of total amount receive

framing in equation form we get;

Amount paid in taxes = \frac{30}{100}x=0.3x = 0.3x

Now Given:

Chan pays 30% in Charity;

So we can say;

Amount paid in charity will be equal to 30% of total amount receive.

framing in equation form we get;

Amount paid in Charity = \frac{30}{100}x=0.3x

Also Given:

Chan pays 30% in old debts;

So we can say;

Amount paid in Old debts will be equal  30% of total amount receive

framing in equation form we get;

Amount paid in Old debts = \frac{15}{100}x=0.15x

Money left with him = $600

Now we can say that Total Amount Receive in bonus will be equal to Amount paid in taxes plus Amount paid in charity plus Amount paid in old debts plus amount left.

framing in equation form we get;

x=0.3x+0.3x+0.15x+600\\\\x= 0.75x +600\\\\x-0.75x=600\\\\0.25x=600\\\\x=\frac{600}{0.25} = \$2400

Hence Chan's Bonus amount was $2400.
