Problema Solution
A man paid $3 more for a dozen Golf balls of one kind than for a dozen of a cheaper kind. If the two dozen balls cost $35.40, how much did he pay for a dozen of each kind?
Answer provided by our tutors
let 'x' represent the cheaper price, then 'x+3' represents the more expensive price and we have:
35.40 = x + (x+3)
solving for 'x' we have x=16.2
the cheaper balls cost $16.20 per dozen, the more expensive balls cost $19.20 per dozen
