Step-by-step explanation:
Find cost of shoes first (7.50)

then divide by 5.30 (47.7/ 5.3= 9)
Alright so if I do remember my math correctly, this is how it goes:
- y = -x^2 + x + 3
- x = -b/2a
- x = -1/2(-1)
- x = -1/-2, which = (1/2)
Not quite sure if this was correct, but if it was, hope this helps and you're welcome! :)
