3/10 because 30 of 100 is 30/100 and didve by 10 and you get 3/10
Let h shoes and s suit:
3s+h=47
7s+2h=107
substitution property:
3s=47-h
s=(47-h)/3
plug it into the other equation and solve for h:
7((47-h)/3)+2h=107
distribute 7 and multiply 3 on both sides:
329-7h+6h = 321
329-h=321
-h=-8
h=8 pair of shoes
s=(47-8)/3=13 suits
