Plug x=3 in the first equation to find y:
4(3)+5y=2
y=-2
so a=-2

Next, plug x=3, y=-2 in the second equation to find b:
6(3)-2(-2)=22
b=22

Answer:

Question wasn't specific enough but I believe the cost=$93.92

Step-by-step explanation:

15.99*3=47.97

12.99*3=38.97

plus 1.99 and 4.99, add them all together

47.97+38.97+1.99+4.99=93.92
