Sabrina spent less than $100. She already bought a toy helicopter at $24.60. 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 Sabrina left to spend on the 2 items
= 100 - 24.60
= $75.40
Round off each number to the nearest tens for a more accurate estimation.
(a) Cube: $23.10 ≈ $20
(b) Guitar: $50.10 ≈ $50
(c) Cushion: $32.10 ≈ $30
(d) Ball: $39.70 ≈ $40
30 + 40 = 70
70 is nearest to 75.40.
Total amount spent on the two items
= 32.10 + 39.70
= $71.80
To use up all her money to buy another 2 items, she cannot exceed $75.40.
The total amount of $71.80 is nearest to and less than $75.40.
So, Sabrina bought (c) Cushion and (d) Ball.
Answer(s): (a) c, d; (b) $71.80
