To determine

Find the number of seeds that Lea plants will germinate.

Answer to Problem 21GP

The number of seeds germinate are $43$ .

Explanation of Solution

Given:

It is given in the question that the total number of seeds are $72$ and approximately $60\%$ of the seeds will germinate.

Concept Used:

In this, use the concept of doing estimation by rounding off the number to simpler numerals.

Calculation:

We can break $60\%$ as $60\%=50\%+10\%$

then,

  $50\%of72$ seeds is $36$

  $10\%of72$ seeds is about $7$ (move the decimal point to the left, round to a whole number of seeds)

So, about $36+7=43$ seeds will germinate.

Conclusion:

The number of seeds are $43$ .
