Four friends are having a barbeque to celebrate a birthday. At the grocery store, the friends pick up the items shown in the list below: HINT: (Remember "of" means to multiply)2.6 lbs. of grapes at $2.90/lb.6 ears of corn on the cob at $0.65 each4.48 lbs. of ground beef at $3.75/lb.2 packages of hamburger buns at $1.44 eachThe friends split the cost of the groceries evenly. How much does each friend owe for the food?

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
