Answer:
S=End amount-Starting amount
Or(with values)
290=890-600
Step-by-step explanation:
So lets get together all our variables.
First, lets create a variable that shows the amount of money saved over the year.
Lets use S, for savings.
Next, lets take our end value, which was 890, and subtract it from our orgninal value.
This will get you the amount of money that Jane earned over the year. This will look like:
890-600
Or
End value=orginal value.
Now S will be equal to the amount of money Jane earned.
So we can write this as:
S=890-600
Or
Amount of money earned=end value-orginal value
Hope this helps!
