all you have to do is make 1 1/4 an improper fraction and then use the keep change flip method.
The statement regarding the expansion of (x + y)" that is correct is D. The coefficients of yn - 1 and yn – 1 both equal 1.
<h3>How to expand?</h3>
It should be noted that for any positive integer, n, the expression of (x + y)^n will be C(n,0)x^n + C+n, 1)x^n-1 .... C(n, n)y^n.
Here, the statement regarding the expansion of (x + y)" that is correct is that the coefficients of yn - 1 and yn – 1 is both equal to 1.

Class B is more variated than Class A.
Answer:B: 133.75$
Step-by-step explanation:
35 + 40 + 50= 125$
The total sales tax is 7%
We can put this into decimal form 7/100= 0.07
Because we want to just add 7% of the value back on we can also add 1 to that number
1.07
125 x 1.07 = 133.75
