A store bought jeans at a cost of $40 a pair. Select all the statements that are true. If the price is marked up 20%, the selling price will be $60.
If the price is marked up 25%, the selling price will be $50.
If the selling price is $65, the price is marked up 50%.
If the selling price is $70, the price is marked up 75%.

True statements:

If the price is marked up 25%, the selling price will be $50.

If the selling price is $70, the price is marked up 75%.

Step-by-step explanation:

Hello! The answer is B) If the price is marked up 25%, the selling price will be $50.

✨ Let me show you how I got the answer... ✨

We know the price of the jeans is $40..

Basically, the percentage is the "Gross Margin".

Then the mark up will be 25%, as the sale price would be $50.

Now that I've showed you how to solve the problem, I hope this helped you!!

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
