Greta and marge are collecting money for a local charity by taking donations outside of busy
local businesses. hoping to collect the most money today, greta gets to her collection spot and
begins collections at 8am. marge wanted to sleep in so she didn't start collections at her spot
until 11am, by which time greta had already collected $45.00. if greta continues to collect
money at a rate of $15 per hour, marge collects money at a rate of $20 per hour and they each
take a 1 hour break at 2pm, at what time will greta and marge have collected the same amount
of money?
plz show full work

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
