The price of an item yesterday was $
135

. Today, the price rose to
$
189

. Find the percentage increase.

step-by-step explanation: the increase = 204 - 120

increase = 84

percent increase = 84/120

percent increase = 70% so of course the percentage is 70%                          ( I hope this helps you )

what is the original number? you forgot to add it.

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)
