Answer 1

Answer:  Jerry's salary is 60% of Alex's salary.

Step-by-step explanation:  Given that Jerry earns 80% of William's salary and William earns 75% of Alex's salary.

We are to find the percentage of Alex's salary that is equal to Jerry' salary.

Let $ x represents the salary of Alex.

Then, Williams's salary is given by

$S_w=75\%\times x=\dfrac{75}{100}\times x=\dfrac{3x}{4}.$

So, Jerry's salary is given by

$S_j=80\%\times S_w=\dfrac{80}{100}\times \dfrac{3x}{4}=\dfrac{4}{5}\times \dfrac{3x}{4}=\dfrac{3x}{5}\times 100\%=60\%\times x.$

Thus, Jerry's salary is 60% of Alex's salary.
