The grocery store sells kumquats for $5.00 a pound and Asian pears for $3.25 a pound. Write an equation in standard form for the weights of kumquats k and Asian pears p that a customer could buy with $18.
I can simplify the formula with the data you gave me to do a simple formula like this: 4.25 k + 2 p = 12 I think this one explains in an easy way this. Hope it's good for you
