Regina wanted an increase in her weekly allowance from $5 to $10, but her parents did her one better. Instead, Regina rolls a fair, six-side die every week, and her allownace for that week will be the number she rolls multiplied by 2. Write and expression where n represents the number on the die that Regina rolls that week.

Hello,

0.5733 = 0.57

Bye :)

0.5733 to the nearest hundredth would be 0.57, here's why:
After a decimal it goes tenth, hundredth, thousandths, ect. So that means the second spot after the decimal is will be the last number. Now look at the thousandths place (3) behind the hundredth place (7), it is 4 or smaller so we will let it rest and the hundredth place will stay a 7.

Final answer:

To calculate interest over time, you need to use the compound interest formula because monthly deposits are being made. However, without more information on how frequently the interest was compounded, we can't find the exact total interest earned from a retirement plan with a 2.5% rate over 42 years with $520 monthly deposits.

Explanation:

The question asks how much interest was gained from investing in a retirement plan with a rate of 2.5% over 42 years. The total monthly deposits were $520. To calculate this, we need to use the simple interest formula which is I=PRT, where 'I' is the interest, 'P' is the principal amount (the initial investment), 'R' is the rate of interest, and 'T' is the period of time.

However, in this case, because the deposits were made monthly, this is not a simple interest problem but a compound interest problem. In such cases, the formula to calculate compound interest (which includes the initial investment amount and the interest earned) is A = P (1 + r/n) ^ nt, where:

• 'A' is the amount of money accumulated after n years, including interest.
• 'P' is the principal amount (the initial amount of money)
• 'r' is the annual interest rate (in decimal)
• 'n' is the number of times that interest is compounded per year
• 't' is the time the money is invested for in years

As we don't have enough information to conclude the precise amount (e.g., whether the interest was compounded annually, quarterly, monthly, or daily), we can't calculate the exact value of the interest earned.
