The total amount of dividend will be:
Total=(Number of issued shares)*(dividend per share)
Number of issued shares=25000
dividend per share=$1.5
thus the total dividend will be:
1.5*25000
=$37500
With scientific notation remember this rule; if the exponent is positive, move the decimal point that many places to the right. If it is negative move it that many places to the left. What that will do is make the number larger or smaller to the correct value.
So for example, if you had to solve 1.02 x 10^4 you would move the decimal four places to the right. So you would end up with 10200.
As another example if you had to solve 1.02 x 10^-2 you would move the decimal two places to the left. That would give you .0120.
So now we are onto your problem. 2.606 x 10^7.
You would move the decimal seven places to the right, because the exponent is positive, that will make your number larger(which would make more sense if you were adding populations, right?).
That would give you 26,060,000 people living in Texas.
From there simply add the two populations together and you will have your answer!
Food is $6,750
Housing is $5,400
Clothing is $2,700
Savings is $3,000
Taxes is $6,750
And other expenses is $2,400
