Answer:

(7;2)

Step-by-step explanation:

If kenny earns 142% of Benny's Salary, how mucho more does Kenny earn than Benny

Sergeeva-Olga [200]

Let Benny's salary = $ K

But kenny earns 142% of Benny's Salary

So, Kenny's salary = 142%of K

Kenny's salary =K $\times \frac{142}{100}$

Kenny's salary = 1.42K

Kenny's income exceeds Benny's by =1.42K - K =$0.42 K

% by which Kenny's salary exceeds by Benny's = $\frac{0.42 \text K}{\text K} \times 100$

% by which Kenny's salary exceeds by Benny's = 42%
