Answer:
20%
Step-by-step explanation:
the number is increased by 3 so you put 3 on 15 and 3/15=1/5=2/10=20/100
The percentage increase in the pay of Nina is 20%.
How to calculate percentage increase?
To calculate the percentage increase work out the difference (reduction) between the two figures you are comparing before calculating a percentage drop. Then, increase the result by 100 after dividing the decrease by the initial number.
% Increase = Increase / Original Number × 100
Nina got the initial pay as $15.00 per hour.
After the increment, her pay increased to $18.00.
The total increment = final pay - initial pay
                 = 18.00 - 15.00
                 = 3.00
Now, the percentage increase = (3/15)×100
                          = 20
Therefore, there is the 20% increment for the pay of Nina.
