in a state with a population of 2000000 the average vitizen spends 6000 on housing each year. what is the total spent on housing

Olenka [21]

Answer:

$1.2 \times 10^{10}$ spents on housing for each year for the state.

Step-by-step explanation:

Given:

Population of State = 2000000

Average Citizen spends on housing = 6000

We need to find total spent on housing for the state.

For finding total spent on housing for state we need to multiply Population of state with average citizen spends on housing.

Total spent on housing for state = Population of State $\times$ Average Citizen spends on housing = $2000000 \times 6000 = 12000000000$

Now expressing the above in scientific notation we get;

Total spent on housing for state = $1.2 \times 10 ^{10}$
