To solve the problem, we can use the following steps:
Determine the difference in mass between the two bags with different numbers of guavas:
Mass of bag with 68 guavas = 7.55 kg Mass of bag with 62 guavas = 6.95 kg Difference in mass = 7.55 kg - 6.95 kg = 0.6 kg
Determine the mass of the 6 extra guavas:
Mass of 6 guavas = ? We can assume that the mass of each guava is roughly the same, so the mass of 6 guavas is proportional to the difference in mass between the two bags:
Difference in mass = 0.6 kg Mass of 6 guavas / 6 = 0.6 kg / 6 Mass of 6 guavas = 0.1 kg
Subtract the mass of the 6 extra guavas from the mass difference to get the mass of the bag:
Mass of bag with no guavas = ? Mass of bag with 68 guavas - mass of bag with 62 guavas = Mass of 6 extra guavas + Mass of bag with no guavas 0.6 kg - 0.1 kg = Mass of bag with no guavas Mass of bag with no guavas = 0.5 kg
Convert the mass of the bag from kilograms to grams:
Mass of bag with no guavas = 0.5 kg = 500 g
Therefore, the mass of the bag when it is empty is 500 grams.
