B.) 3.250*106 days

I figured it out!! Yay!

You take 7.8 and divide it by 24 which will get you 0.325
In order to get it match one of the options, multiply it by 10 (which will add 1 to 105!) Leaving you 3.25*106

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.

Juan and his friends bought drinks for a charity event. The table shows the numbers of each kind of drink bought, and the amount
OverLord2011 [107]

Answer: soda costs $3

Lemonade costs $4

Water costs $2

Step-by-step explanation:

The table shows the number of Soda, lemonade and water bought by Juan, Lee and morris and the total amount each of them spent in buying these drinks

Juan spent $43 on 5 bottles of soda, 4 bottles of lemonade and 6 bottles of water

Lee spent $34 on 2 bottles of soda, 5 bottles of lemonade and 4 bottles of water

Morris spent $41 on 3 bottles of soda, 7 bottles of lemonade and 2 bottles of water

Let price of soda be x

Let price of lemonade be y

Let price of water be z

From the table

5x + 4y + 6z = 43 - - - - - - 1

2x + 5y + 4z = 34 - - - - - - 2

3x + 7y + 2z = 41 - - - - - - -3

Multiply equation 1 by 2 and equation 2 by 5

10x + 8y + 12z = 86

10x + 25y+20z =170

Subtracting

-17y -8z= -84 - - - - - -4

Multiply equation 2 by 3 and equation 3 by 2

6x + 15y+12z = 102

6x + 14y + 4z = 82

Subtracting

y + 8z = 20 - - - - - 5

Add equation 4 and equation 5

-16y = -64

y= -64/-16 = 4

Put y= 4 in equation 4

-17 × 4 -8z = - 84

-68-8z = -84

-8z = -16

z = -16/-8 = 2

Put y = 4 and z = 2 in equation 1

5x + 4×4 + 6×2 = 43

5x + 16 + 12 = 43

5x = 43-28= 15

x = 15/5 = 3
