Answer:
$158.8
Step-by-step explanation:
There are 12 months in 1 year.
If in 1 year, it looses value of 10.3%, so in a month it will loose value of:
10.3%/12 = 0.8583% per month
So, to find the decreased value (in dollars) per month, we got to find 0.8583% of 18,500 dollars.
First, we need to convert percentage to decimal by dividing by 100. Then we multiply that to 18,500 to get our answer. So:
0.8583% = 0.8583/100 = 0.008583
Now,
0.008583 * $18,500 = $158.7855
Rounded to nearest tenth (1 decimal pae) = $158.8
