Saving Estimation Reasonableness Assessment
Estimate first, then decide whether each result makes sense. Show your calculations for written questions. Use 26 fortnights = 1 year and 12 months = 1 year.
Choose the most reasonable answer
Circle one option for each question.
1.Lachlan puts $250 into savings every fortnight. About how many fortnights will she need to save $6,000?

- About 24 fortnights
- About 36 fortnights

2.Hamish saves $180 each fortnight. He estimates that after one year he will have about $4,700. Is his estimate reasonable?
- Yes. 26 fortnights at about $180 is close to $4,700.
- Yes. 12 fortnights at $180 is close to $4,700.
- No. One year has 52 fortnights, so he will have about $9,400.
- No. $180 each fortnight is less than $1,000 for the year.
3.Luca needs $7,200 and saves $300 each fortnight. Which statement best checks his estimate of the time needed?
