Sami's bank account earns 4% simple interest per year. If Sami deposits $500, how much simple interest will she earn in one year

timurjin [86]

Answer:

$20 simple interest.

Step-by-step explanation:

The simple interest that Sami earns is 4% of her deposit since she is trying to find how much she will earn in one year (given that the interest rate is 4% per annum).

$\$500\times4\%=\$20$

∴ Sami earns $20 simple interest in one year.

Hope this helps :)

How do you complete <br>-6/5k=12

Inessa [10]

Here, I'll help you a little
rewrite the equation as -6k/5 = 12
multiply both sides by 5
-6k=60
divide both sides by -6 to isolate k
k = -10

Hope this helps :)
