An instrument store gives a 20% discount to all students off the original cost of an instrument. During a back to school sale an additional 25% is taken off the discounted price. Janice, a student at the incredible Thornridge High School, purchases a flute for $306. How much did it originally cost?

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
