How I did It?

first I went 50 times 30 but to make it easier i mt that equalled 15 and added two 0 on to it Then i went 50 times 5 and that equals 250 and then i went 7 times 30 and that equals 210 and then i went 7 times 5 and that equals 35 and then i added 1500+210+35 and put it all together and it equalled 1,995 and thats how i did it.
