Valen paid $2.95 for posting a package overseas. What was the greatest possible mass of the package that Valen posted?
$1 = 100¢
$2.95 = 2.95 x 100 = 295¢
Amount that Valen paid for the additional sets of 10 g for the overseas package
= 295 - 45
= 250¢
Number of sets of 10 g that Valen paid for the overseas package
= 250 ÷ 10
= 25
Mass of 25 sets of 10 g for the overseas package
= 25 x 10
= 250 g
Greatest possible mass of the overseas package
= 60 + 250
= 310 g
Answer(s): 310 g
