Greg spends $0.45 on an eraser and $0.30 on a pen. how much money does greg spend?

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

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!
