The answer is D. because if there is 32 total, and 18 of them are girls, that means that there are 14 boys . with the question asking for girl/boy ratio it would have to be 18/14 in that order . if you divide 18 and 14 by two, they simple down to 9/7 . making the answer D.
Answer:
Find out the what does the value 500 represent in this situation .
To prove
As given
The amount of money in a savings account after t years is represented by the function.
Exponential function for amount is given by .

Wher a is the initial value, r is the rate in decimal form and t is the time.
Compare the functions
and

Thus a = 500
Therefor $500 is the initial value .
Computer= $1200
You: makes $300 deposit
Computer= $900
You pay 10 percent interest and pay 4 quarterly installments.
*This means that you pay 4 times in a year. You pay once every 3 months + interest. So basically you pay will need to pay four times in one year to fully pay back your debt.
Interest-money paid regularly at a certain rate for the use of money lent, or for delaying the repayment of debt
You would pay $236.36 per every 3 months
Paying off $900 on 10% interest would mean that you pay a total of $945.45 in the time frame of a year (4 quarterly installments).
The domain of any graph depends on the vertex as well as the asymptotes. You can easily tell if the domain is all real numbers by looking at the graph and seeing that it goes clearly from -infinity to +infinity. If there is an asymptote that blocks it, then it will not be all real numbers.
