An instrument store gives 10 percent discount off the original cost of an 15 is taken discounted price Julie buys a flute for 306 how much did it originally cost?

Solution:

Let the original cost be $$x$$

Discount $$= 10%$$

$$= \frac{10}{100}\times x = 0.10x$$

Therefore, the discounted price

$$= x -0.10x = 0.90x$$

Given that the discount price is $$306$$

According to the question

$$0.90x =306$$

$$x =\frac{306}{0.90}$$

$$x = 340$$

Therefore, the original price of the flute was $$\bf340.$$
