B. 3.5p+5p<300

C. 3.5p+5p≥300

Respuesta :

The answer is D because he can spend 300 or less and 3.5 per person plus the 5 dollars for food per person

Each person will cost 3.50 for skates and 5.00 for food,
therefore, 3.50p + 5.00p = total cost for p people.
This number has to be at most 300, since that's Xian's budget (fairly baller for a birthday party). 
Therefore, 
Total cost for p people ≤ 300
Plugging in our cost for p people:
3.50p + 5.00p ≤ 300
Answer is D
