Answer:
3.78 * 10^10
Step-by-step explanation:
Total number of employees in the department store chain = 1.8*10^6
Average annual wage for the employees = 2.1* 10^4
Hence the total wage to be paid out to the employees is given by the product of the two numbers:
1.8 * 10^6 * 2.1 * 10^4 = 1.8 * 2.1 * 10^6 * 10^4 = 3.78 * 10^(6+4) = 3.78 * 10^10
So the total wages paid by the store chain per year is 3.78 * 10^10 or in other words, 37800000000 .
