If (x, 4) lies on the line 3x+y=10, we can just substitute the values in
x=x and 4=y
3x+4= 10
Subtract 4 from each side
3x= 6
Divide by 3 on each side
x=2
so the x in (x,4) must be 2

Turn 5% into a decimal which is 0.05, then multiply by 2.95 = 0.1475
round it off, which is 0.15
so $0.15 is the tax and if ur looking for the total price then add $2.95 to $0.15
