All you have to do is just put the same variable on the same side as each other.
Answer:
the correct answer is 22 and 12
Step-by-step explanation:
Divide each term in the y column by 2 to go from this list {8, 2, 0, 2, 8} to this list {4, 1, 0, 1, 4}
This list {4, 1, 0, 1, 4} is a bunch of perfect squares so it suggests that y = x^2
However we must double the values to get back to the original list. So the rule is y = 2*x^2
Multiply the cost of the game by the sales tax:
7% tax = 0.07
50 x 0.07 = 3.5
The tax would be $3.50
