Geoff estimates that 27% of 121 is about 30. Which of the following statements is true?

Question

His estimate is way too high.
His estimate is way too low.
There is not enough information.
His estimate is good.

Answer 1

To evaluate Geoff's estimate of 27% of 121 being about 30, we can calculate the actual value:

1. Calculate 27% of 121: \[ 0.27 \times 121 = 32.67 \]

Geoff estimated that 27% of 121 is about 30.

2. Compare the estimate to the actual value:
   • The actual value (32.67) is higher than the estimate (30).

Since his estimate (30) is lower than the actual value (32.67), we can conclude that:

His estimate is way too low.
