Best ResponseYou've already chosen the best response.0Each year, Terrell buys a plane ticket to visit his grandmother for a week. Last year, he paid $130. This year, he paid $143. What was the percent increase in the cost of his plane ticket? Show your work.

Best ResponseYou've already chosen the best response.0that is the question this is my answer: amount of change/original amount = percent of change/100 143/130 = x/100 143 x 100 = 14,300 130 x 1 = 130 so we now have the fraction 14,300 over 130 which reduces to 110 over 1 which is actually just 110. So x = 110. Our percentage increase is 110.

Best ResponseYou've already chosen the best response.0Well, only a 10% increase. Realize that 100% is the old amount of 130. So if youre going to increaseby 100% + 10%, bit much, eh?

Best ResponseYou've already chosen the best response.1\[\frac{ 143130 }{ 130} = \frac{ x }{ 1000 }\]

Best ResponseYou've already chosen the best response.0so i would multiply across and add a 1 under 100, no?

Best ResponseYou've already chosen the best response.0(new value  old value) / old value (143  130) / 130 = 13/130 = .1 .1 x 100 = 10% your answer is correct...10% increase
