The mass of a box with 3 basketball sets is 7.53 kg.
The mass of the empty box is 6.63 kg.
- What is the mass of each basketball set?
- What is the mass of a box with 4 basketball sets?
(a)
Mass of 3 basketball sets
= 7.53 - 6.63
= 0.9 kg
Mass of 1 basketball set
= 0.9 ÷ 3
= 0.3 kg
(b)
Mass of 1 box with 4 basketball sets
= 6.63 + 4 x 0.3
= 6.63 + 1.2
= 7.83 kg
Answer(s): (a) 0.3 kg; (b) 7.83 kg
