Part (b)

1.If next year the number of accounts increases by 20%, the number of technicians has to be increased by 20%, too. How many new technicians have to be hired next year?
Please note: your result has to be rounded to the whole number.
2.What will be the total number of technicians working for the company next year?

8 x .2 = 1.6

Rounded, how many technicians will need to be hired?

To answer part (b) of the question, we need to calculate the number of new technicians that have to be hired next year and the total number of technicians working for the company.

1. To find the number of new technicians that have to be hired next year, we first need to calculate 20% of the current number of accounts. Let's assume the current number of accounts is 8. To calculate 20% of 8, we multiply 8 by 0.2:

8 x 0.2 = 1.6

However, the result of 1.6 is not a whole number since it includes decimal places. So, we need to round it to the nearest whole number. When rounding, if the decimal part is 0.5 or higher, we round up, and if it is below 0.5, we round down. In this case, 1.6 is closer to 2, so we round it up:

Rounded, the number of technicians that need to be hired next year is 2.

2. To find the total number of technicians working for the company next year, we need to add the number of current technicians to the number of new technicians. Let's assume the current number of technicians is 10. Adding the 2 new technicians to the current number:

10 (current technicians) + 2 (new technicians) = 12

Therefore, the total number of technicians working for the company next year would be 12.
