Work out the value of y when x = 4 30 points

y = 54/25 when x = 4.

Step-by-step explanation:

y is given by the equation:

Where p and q are numbers.

We are also given that when x = 1, y = 10 and when x = 6, y = 0.7776.

And we want to determine the value of y when x = 4.

Since y = 10 when x = 1:

Simplify:

Any number (except for zero) to the zeroth power is one. Hence:

Thus, our equation is now:

When x = 6, y = 0.7776. Thus:

Simplify and divide both sides by ten:

Take the fifth root of both sides:

Use a calculator. Hence:

Our completed equation is:

Then when x = 4, y equals:

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
