Step-by-step explanation:

We are given

The student council earned $1.25 for every cup of hot chocolate it sold

total number of cup is 375

We can see that first term is 1.25x

and we have

The student council earned $1.25 for every cup of hot chocolate

so, to find total cost of hot chocolate , we multiplied 1.25 with x

that's why

x must be the number of cups of hot chocolate sold

So the answer must be C

Answer:

Step-by-step explanation:

$\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3$

$(3x^2)^\frac{1}{2} = 3^\frac{1}{2} x$

Remember that $\frac{x^b}{x^c} =$ x^(b-c)

Using that $\frac{3^\frac{1}{2}x }{3^\frac{1}{2} }$ =3^(1/2x-1/2)=3^((x-1)/2)

$3^\frac{x-1}{2} =3^1$

So we can say: $\frac{x-1}{2} =1$ , because the bases are the same

We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
