\frac{x}{3} + 1 = 3

First, multiply both sides by 3. / Your problem should look like: x + 3 = 9.
Second, subtract 3 from both sides. / Your problem should look like: x = 9 - 3.
Third, simplify 9 - 3 to 6. / Your problem should look like: x = 6, which is your answer.

Jamal bought a diamond ring at a 20% discount. He paid $2640 for the ring. Naomi bought a similar ring but was given a discount
Fudgin [204]

Answer: 72%

Step-by-step explanation:

Set Jamal's original ring price = x

x - x(0.2) = 2640\\x(1-0.2)=2640\\x(0.8)=2640\\x=\frac{2640}{0.8}=3300

Jamal's original ring price = $3300

Set Naomi's discount = y

3300-3300(y)=924\\=3300(1-y)=924\\1-y=\frac{924}{3300} \\-y=\frac{924}{3300} -1\\y=1-\frac{924}{3300}=1-0.28=0.72

Naomi's discount is 0.72 = 72%
