The mass of a box with 9 basketball sets is 5.05 kg.
The mass of the empty box is 1.63 kg.
- What is the mass of each basketball set?
- What is the mass of a box with 8 basketball sets?
(a)
Mass of 9 basketball sets
= 5.05 - 1.63
= 3.42 kg
Mass of 1 basketball set
= 3.42 ÷ 9
= 0.38 kg
(b)
Mass of 1 box with 8 basketball sets
= 1.63 + 8 x 0.38
= 1.63 + 3.04
= 4.67 kg
Answer(s): (a) 0.38 kg; (b) 4.67 kg
