Answer:
A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).
Step-by-step explanation:
Bruce does have enough money to buy the video game.
x/42 = 30/100
x=12.60 - This is the amount of money the video game is without tax
x/12.60 = 5/100
x=0.63 - sales tax amount
0.63+12.60=13.23 - amount of video game with tax
1<x<4 is the answer for the question
