Start by making an equation.
D is your variable.
12d=1500
Then, divide each side by 12 because there are 12 months.
12d=1500
—- ——
12. 12
d=125
Diana donates $125 per month to a charity. This is because when you have a yearly sum that is paid per month, but you don’t know the per month rate, you divide the yearly amount by 12 because there are 12 months.
I really hope this helps and you get a good grade!!
