Jen spent less than $80. She already bought a toy helicopter at $24.10. 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 Jen left to spend on the 2 items
= 80 - 24.10
= $55.90
Round off each number to the nearest tens for a more accurate estimation.
(a) Blocks: $32.80 ≈ $30
(b) Cube: $20.50 ≈ $20
(c) Aeroplane: $53.70 ≈ $50
(d) Doll: $42.30 ≈ $40
30 + 20 = 50
50 is nearest to 55.90.
Total amount spent on the two items
= 32.80 + 20.50
= $53.30
To use up all her money to buy another 2 items, she cannot exceed $55.90.
The total amount of $53.30 is nearest to and less than $55.90.
So, Jen bought (a) Cube and (b) Block.
Answer(s): (a) a, b; (b) $53.30
