Two produce stores sell watermelons by the pound. At Jack's store, he uses the equation y = 0.39x to calculate the cost of a watermelon that
weighs x pounds.
At Molly's store, she charges $4.20 for a 12-pound watermelon and $5.25 for a 15-pound
watermelon.
If a watermelon weighs 20 pounds, at which store will the watermelon cost less, and by how
much?
A. Jack's store is less expensive by $0.80.
B. Jack's store is less expensive by $0.04.
C. Molly's store is less expensive by $0.80.
D. Molly's store is less expensive by $0.04.

no not all of them.

step-by-step explanation:

some of them have a square base.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
