Math word problem (percentage word problem) what is the percent increase in price?
How would you work this problem out?
Betty took a Doll to the antique store. The Original price tag says $6.80. the antique store says the Doll is now worth $84.00 What is the percent increase in price? Round to the nearest hundredth.
I believe you can use the is/of = %/100 formula for this question. I’m not entirely sure if this is the right answer, though it could possibly be because it makes sense.
Work:
84/6.8=%/100 —– multiply the 100 to 84 to make it 8400/6.8 = %
so your percent would equal to 1235.29% increase, which sounds about right, because 1000% increase would be $68.
Hope this is correct
