Tony because he spent $19 while Mario spent $18. To explain, you would multiply 3 by $4 because Tony bought 3 of the $4 packs of pencils. Therefore, he would have spent $12. In addition, add $7 to $12, you get $19. On the other hand, Mario bout 4 of the $6 binders. That would mean he spent $24 on binders However, he had a $6 coupon which means he can take $6 off the total price of $24. That would mean subtracting $6 from $24. That would get Mario $18

Answer:
D
Step-by-step explanation:
-3x + 3y = 9 (1)
2x - 7y = -14 (2)
From (1),
3y= 9 + 3x
y = 3 + x
Using (2),
2x - 7(3 + x) = -14
2x - 21 - 7x = -14
-5x = 7
x = -7/5 = -1⅖
y = 3 + x = 3 - 7/5 = 8/5 = 2⅗
