Answer is c. $62.99
Step by step
89.99 x 70% = x
89.99 x .70 = 62.99
Hint: If the dress was 30% off, it’s cost is 70%
You can also do this in two steps
89.99 x 30% = discount of $27.
Then
89.99 - $27 = $62.99
2.5(x - 9) = 8
Distribute the 2.5
2.5x - 22.5 = 8
Add 22.5 to both sides
2.5x = 30.5
Divide both sides by 2.5
x = 12.2
