Nicole spent less than $70. She already bought a toy helicopter at $25.90. 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 Nicole left to spend on the 2 items
= 70 - 25.90
= $44.10
Round off each number to the nearest tens for a more accurate estimation.
(a) Blocks: $26.80 ≈ $30
(b) Cube: $15.80 ≈ $20
(c) Aeroplane: $47.10 ≈ $50
(d) Doll: $41.90 ≈ $40
30 + 20 = 50
50 is nearest to 44.10.
Total amount spent on the two items
= 26.80 + 15.80
= $42.60
To use up all her money to buy another 2 items, she cannot exceed $44.10.
The total amount of $42.60 is nearest to and less than $44.10.
So, Nicole bought (a) Cube and (b) Block.
Answer(s): (a) a, b; (b) $42.60
