Jaslyn spent less than $130. She already bought a toy helicopter at $29.10. 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
= 130 - 29.10
= $100.90
Round off each number to the nearest tens for a more accurate estimation.
(a) Aeroplane: $45.70 ≈ $50
(b) Blocks: $33.70 ≈ $30
(c) Teddy bear: $43.20 ≈ $40
(d) Lego: $65.50 ≈ $70
30 + 70 = 90
90 is nearest to 100.90.
Total amount spent on the two items
= 33.70 + 65.50
= $99.20
To use up all her money to buy another 2 items, she cannot exceed $100.90.
The total amount of $99.20 is nearest to and less than $100.90.
So, Jaslyn bought (b) Blocks and (d) Lego.
Answer(s): (a) b, d; (b) $99.20
