I think y is always 3 less than x. So for the first blank it would be 3 less than -1, that is -4. That makes the second blank -3. The third -8. And the last, -5.
The equation might be x-3=y
I might be wrong, please tell me if this is correct.
The tax that Mark had to pay is calculated by multiplying the base price of the video game and the decimal equivalent of the tax percentage. That is,
tax = ($49.99) x (0.08)
= $3.9992
Thus, Mark had to pay approximately $4 for the tax.
The ratio in simplest form is 2:5
