Claire decides that to solve this problem by setting up a proportion. What should her proportion look like?A) 300100 = x450B) x100 = 300450C) x100 = 450300D) 450100 = x300

"Artie needs to save $450 to buy the new bicycle that he wants. He currently has $300. What percent of the cost of a new bicycle has he saved?"

Write and solve an equation of ratios (proportions)"

 $300         x                                                                   
--------- = -------   which  results in x = 300/450 = 0.667 (approx.) or 20/3.  
 $450         1

and this works out to 67%    (answer)
