Ralph chase graduated from college with a dept of $20000. He had taken out two different kinds of loans : a government loan at 3.3% APR ( annual percentage rate, or interest after one year) and a private loan at 4.9% APR . If his total interest after one year was $804 , how much money did he borrow from each source ?

Answers

Answer:

Ralph borrowed $11,000 from the government source and $9,000 from the private source.

Step-by-step explanation:

Let:

x = government loan

y = private loan

x + y = 20,000 ............................................ (1)

x = 20,000 - y ............................................. (2)

0.033x + 0.049y = 804 ............................ (3)

Substitute equation (2) into (3) for x, we have:

0.033(20,000 - y) + 0.049y = 804

660 - 0.033y + 0.049y = 804

0.016y = 804 - 660

0.016y = 144

y = 144 / 0.016 = $9,000

Substitute $9,000 for y in equation (2), we have:

x = 20,000 - 9,000 = $11,000

Therefore, Ralph borrowed $11,000 from the government source and $9,000 from the private source.

A digital camera for $249.99 at 4% sales tax

Answers

First, change the 4% into a decimal. Once thats changed, it will be 1.04
Multiply 1.04 by the amount of the cost, to get your answer.
But, to make this easier, and to not go through more work, lets round your money amount to $250
Now, all you have to do is multiply.
$250 · 1.04 ≈ $260
So, your answer for $250 with 4% (1.04) percent sales tax would be a grand total of:
$260

Solve the equation using the balance method

Answers

ballance method is just a fance method of helping you remember to DO THE SAME THING TO BOTH SIDES OF AN EQUATION to keep it ballanced


-10=2(-3x+1)
divide BOTH SIDES by 2 to get rid of that 2 in front
-5=-3x+1
minus BOTH SIDES 1
-6=-3x
divide BOTH SIDES by -3
2=x
