Can you solve this and tell me how you did it?
An instrument store gives a 10% discount to all students. During back to school week, they give an extra 15% off to all students. If a student went to this store, and paid $306 for a flute, what was the original cost?

(orig. price*.90).85=$306
.765*orig. price=$306
orig. price=306/.765
Orig. Price = $400
I would think that the store would take the 10% discount off first since it’s the usual discount so that would be .90 of the original price. Once you get the new amount then the addt’l 15% will be deducted hence .85 of the new price. So, use the equation and solve for the original price. Hopes this helps!

This is how I figured it.
A/306=25/100
cross multiply
A100=7650
divide by 100
A=76.5
add this to the discounted amount to get the original cost of the instrument.
306 + 76.5= 382.50

The original cost was $408, to check $408 x 75% (100% – 25% total discount).
