Final answer:
Levonne's method of rounding 38% of 63 to 40% would be considered reasonable for a quick approximation since both the estimated (25.2) and actual (23.94) are fairly close. However, rounding to 40% of 240 is not appropriate for this estimation.
Step-by-step explanation:
The question asks whether the estimate reasonable when Levonne estimated 38% of 63 by rounding 38% to 40%. If we round up 38% to 40%, the estimation would be:
40% of 63 is the same as 0.40 x 63 = 25.2
However, 38% of 63 is 0.38 x 63 = 23.94
Comparing the actual calculation with the estimate:
- Actual: 23.94
- Estimate: 25.2
Since the estimate is fairly close to the actual amount, Levonne's method for estimation could be considered reasonable for a quick approximation. However, it appears Levonne actually rounded to 40% of 240, not 63, which is not an appropriate method for estimating 38% of 63 and would hence not be considered a reasonable estimate.
