Answer:

21 students were in the class.

Step-by-step explanation:

The information in the question tells you that 4/7 of the class is girls.

That means that the remainder of the class is 1 - 4/7 = 3/7 boys

Let the total in the class = x

(3/7)x = 9           Multiply by 7

(3/7)*7*x = 9 * 7 Simplify the right and left

3x = 63              Divide by 3

3x/3 = 63/3

x = 21

There were 21 students in the class.

Answer:

A. $307,172.72

Step-by-step explanation:

Inez has to pay 4 percent in closing costs and 16 percent for the down payment on a purchase of $225,500 with an ARM.

4% + 16% = 20%

lnez has to pay 20% of $225,500

= 225,500*20/100

= 225,500*0.2

= $45100

lnez has to pay $45100.

Over the life of the loan, lnez will pay $262,072.72

Now we have to add down payment, closing cost and the payment over the life of the loan.

$45100 + $262,072.72

= $307,172.72

Answer: A. $307,172.72
