Answer: The total cost of the bike is $974.53
How to solve: To solve this you’d take the net price which is $887.95 and add it with the sells tax which is 9.75%.
This basically means that you have to multiply the x and y values by 3. So 2 time 3 is 6. And -7 times 3 is -21. So the new coordinations are (6, -21)
