Question #1:

To find the percentage of boy's in the class, divide.

9 / 36 = 0.25

0.25 * 100% = 25% (boys in the class)

We can write this proportion as 9/36 since this is the same as 25%.

Question #2:

We know that the ear buds in both options cost $125.

The earbuds online are on a 20% discount.

The earbuds in store are on a 90$ sale

Lets find the discount for the online pair.

20% = 0.2

125 * 0.2 = 25

125 - 25 = $100 (price after discount)

After solving we can see that the earbuds in store are a better price. So, you will purchase the ear buds in store.
