Andrew paid an agency 10% of his first year's rent for finding him an apartment. his rent is $1,800 per month. what is the amount of the commission that andrew paid the agency

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
