Caden paid $2.60 for posting a package overseas. What was the greatest possible mass of the package that Caden posted?
$1 = 100¢
$2.60 = 2.60 x 100 = 260¢
Amount that Caden paid for the additional sets of 10 g for the overseas package
= 260 - 60
= 200¢
Number of sets of 10 g that Caden paid for the overseas package
= 200 ÷ 10
= 20
Mass of 20 sets of 10 g for the overseas package
= 20 x 10
= 200 g
Greatest possible mass of the overseas package
= 60 + 200
= 260 g
Answer(s): 260 g
