Blanche has recently inherited $8000 which she wants to deposit into a savings account. she has determined that her two best bets are an account that compounds annually at an annual rate of 5.1% and an account that compounds quarterly at an annual rate of 3.1%. which account would pay blanche more interest?

The first account will give more interest after one year.

Step-by-step explanation:

Blanche has to invest $8000 in a saving account.

(i) One account gives a 5.1% annual interest compounded annually.

So, after one year she will get an interest of dollars

(ii) In another account gives 3.1% annual interest compounded quarterly.

So, the quarterly interest is %.

Hence, after one year she will get an interest of dollars (Approximate)

Therefore, the first account will give more interest after one year.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
