Jaslyn spent less than $110. She already bought a toy helicopter at $22.20. 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 Jaslyn left to spend on the 2 items
= 110 - 22.20
= $87.80
Round off each number to the nearest tens for a more accurate estimation.
(a) Aeroplane: $48.60 ≈ $50
(b) Blocks: $31.10 ≈ $30
(c) Teddy bear: $36.50 ≈ $40
(d) Lego: $62.80 ≈ $60
50 + 40 = 90
90 is nearest to 87.80.
Total amount spent on the two items
= 48.60 + 36.50
= $85.10
To use up all her money to buy another 2 items, she cannot exceed $87.80.
The total amount of $85.10 is nearest to and less than $87.80.
So, Jaslyn bought (a) Aeroplane and (c) Teddy Bear.
Answer(s): (a) a, c; (b) $85.10
