Answer:
Given - Ratio of boys to girls is 3 : 1
Total 36 students
To find - No. of girls
Solution
Let the ratio be 3x and X
3x + X = 36
4x = 36
x = 36/4
x= 9
1x = 9
There are 9 girls in the class
First, we calculated the discounted price which would have been paid by Keith. That is the product of 85% and $36,000.
($36,000) x (85%) = $30,600
Then, after negotiating to pay 9% off the sale price, he will only need to pay 91% of the sale price. The new price would be,
($30600) x (0.91) = $27846
Thus, Keith will only need to pay $27,846.
To find the difference, we are going to destroy the parenthesis first, and then, we are going to perform the operations. Remember that to destroy a parenthesis preceded by a negative sign (-), you should change the signs of the factors inside the parenthesis:
Now we can factor both numerator and denominator and simplify:
We can conclude that the difference in simplest form is:
