The mass of a box with 9 basketball sets is 5.19 kg.
The mass of the empty box is 3.21 kg.
- What is the mass of each basketball set?
- What is the mass of a box with 10 basketball sets?
(a)
Mass of 9 basketball sets
= 5.19 - 3.21
= 1.98 kg
Mass of 1 basketball set
= 1.98 ÷ 9
= 0.22 kg
(b)
Mass of 1 box with 10 basketball sets
= 3.21 + 10 x 0.22
= 3.21 + 2.2
= 5.41 kg
Answer(s): (a) 0.22 kg; (b) 5.41 kg
