Reggie paid $4.95 for posting a package locally. What was the greatest possible mass of the package that Reggie posted?
$1 = 100¢
$4.95 = 4.95 x 100 = 495¢
Amount that Reggie paid for the additional sets of 10 g for the local package
= 495 - 55
= 440¢
Number of sets of 10 g that Reggie paid for the local package
= 440 ÷ 10
= 44
Mass of 44 sets of 10 g for the local package
= 44 x 10
= 440 g
Greatest possible mass of the local package
= 60 + 440
= 500 g
Answer(s): 500 g
