Answer:
about $709 per month
Step-by-step explanation:
Okay, so in order to solve this question, we should follow this formula:
3,000 + 24x 20,000
where 24 is the amount of time we have and x is the variable we are using as to show the unknown amount of money earned per month.
3,000 + 24x 20,000
-3,000 -3,000
24x 17,000
/24 /24
x approximately 709 dollars
so, we substitute x for 709
3,000 + 24(709) 20,000
3,000 + 17,016 20,000
20,016 20,000
which is true
Hope this helps :)
