Sport City offers a better deal.

Step-by-step explanation:

I've been taught to use convert the percentages to decimals, it makes it easier.

For example, 15%= .15 and 20%= .2

First, you would multiply 180 and .15 (which equals to 27). Then subtract 27 from 180 (180-27= 153)

Same goes for the other. First multiply 200 and .2 (which equals to 40). Then subtract 40 from 200 (200-40= 160)

Soo, the tennis racket at Sport City is offering the best deal.

all it means is function 3

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
