Answer:
Sport City offers a better deal.
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.
