Maria bought 5 birthday cards from a store. The price of each card was the same. After she bought the cards, her account balance showed a change of -$15.95. What would have been the change to Marta's account balance had she only bought 1 card from the store?
$3.19
B -$3.19
C $4.50
D -$4.50

B

Step-by-step explanation:

If the charge for five cards was -15.95, the charge for one card is -3.19 because (-15.95)/5 = -3.19

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
