The mass of a box with 4 basketball sets is 6.95 kg.
The mass of the empty box is 4.75 kg.
- What is the mass of each basketball set?
- What is the mass of a box with 3 basketball sets?
(a)
Mass of 4 basketball sets
= 6.95 - 4.75
= 2.2 kg
Mass of 1 basketball set
= 2.2 ÷ 4
= 0.55 kg
(b)
Mass of 1 box with 3 basketball sets
= 4.75 + 3 x 0.55
= 4.75 + 1.65
= 6.4 kg
Answer(s): (a) 0.55 kg; (b) 6.4 kg
