Victoria spent less than $80. She already bought a toy helicopter at $28.20. She tried to use up all her money and bought another two items.
- Name the two items. Give your answers in letters. (Eg a, b)
- What was the total cost for the two items?
(a)
Estimated amount that Madam Victoria left to spend on the 2 items
= 80 - 28.20
= $51.80
Round off each number to the nearest tens for a more accurate estimation.
(a) Blocks: $32.40 ≈ $30
(b) Cube: $17.10 ≈ $20
(c) Aeroplane: $49.20 ≈ $50
(d) Doll: $37.60 ≈ $40
30 + 20 = 50
50 is nearest to 51.80.
Total amount spent on the two items
= 32.40 + 17.10
= $49.50
To use up all her money to buy another 2 items, she cannot exceed $51.80.
The total amount of $49.50 is nearest to and less than $51.80.
So, Victoria bought (a) Cube and (b) Block.
Answer(s): (a) a, b; (b) $49.50
