Answer:

basketball = 7.75 dollar

pump = 23.25 dollar

Step-by-step explanation:

basketball and a pump costs = b + p = 31 dollars

Assume that ;

basketball = b

pump = p

Given that ;

basketball costs three times as much as the pump

3b = p

Put value of p in total cost equation :

b + p = 31

b + 3b = 31

b = 31/4 = 7.75

Put value of b in same equation

b + p = 31

p = 31 - 31/4

  = 93/4 = 23.25
