Ann deposited money into two new accounts, A and B. Account A earns 5 percent simple annual interest and account B earns 8 percent simple annual interest. If there were no other transactions in the two accounts, then the amount of interest that account B earned in the first year was how many dollars greater than the amount of interest that account A earned in the first year?

Respuesta :

Answer:

Account B will generate 1.6 times as much interest as Account A assuming initial investment values are equal

Explanation:

Annual interest is determined by multiplying the principle amount by the interest rate. In this case, if amount X is deposited in account A and amount Y is deposited in account B, the interest generated in each account will be:

[tex]Account A = X*5\% = 0.05X[/tex]

[tex]Account B = Y*8\% = 0.08Y[/tex]

As absolute values of investment are not specified, exact difference in amount of interest cannot be determined. However, ratios can calculated.

[tex]\frac{Account B}{Account A} = \frac{0.08Y}{0.05X}[/tex]

If it can be assumed that the investment in both accounts is equal (X = Y), the equation can be simplified as below:

[tex]\frac{Account B}{Account A} = \frac{0.08Y}{0.05Y}[/tex]

[tex]\frac{Account B}{Account A} = 1.6[/tex]

Thus, Account B will generate 1.6 times more interest than Account A
