vinnie is searching online for airline tickets. Two weeks ago, the cost to fly from to was $250. Now the cost is $370. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?

40.48%

Step-by-step explanation:

Two weeks ago, the cost to fly = $250

Now the cost is $370. With additional baggage fee. $370+$50 = $420

% Increase = 420 - 250 / 420 * 100%

% Increase = 170 / 420 * 100%

% Increase = 0.4048 * 100%

% Increase = 40.48%

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
