Ariane borrows 500 on a 2 year loan she is charged 5 percent simple interest per year how much interest is she charged for 2 years what is the total amount she has to pay back?

She gotta pay $550 or $551.25.

Step-by-step explanation:

To find percent, u gotta multiply 500 by .05, since it's 5 percent, nd 5 percent is .05. When I did that, I got 25, nd 25 is for one year, but u wanna kno for two years, so 25 + 25 is 50. $500 + $50 is $550.

After one year, the total price is $525, so Ian kno if u was supposed to do %5 of $525, but ehrn I did I got $551.25.

Ion really kno nun bout interest rates, but I kno one of these answers is right.

Complete Question

The body of 154-pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum.

Based on this information, the number of milligrams of aluminum in the body is how many times the number of milligrams of gold in the body?

300 times

Step-by-step explanation:

From the above question, we are told:

The body of 154-pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum.

We create a proportion

2 × 10^-1 mg of gold : 6 × 10^1 mg of aluminum

= 0.2 mg of gold : 60 mg of aluminum

Therefore, the number of milligrams of aluminum in the body is how many times the number of milligrams of gold in the body is calculated as:

60mg ÷ 0.2 mg

= 300

Therefore, the number of milligrams of aluminum in the body is 300 times the number of milligrams of gold in the body
