The dress originally costs $120.
In order to find this, you need to divide the current cost by the percentage you are paying for. Since it's 75% off, you are paying for 25% of the dress's original cost. Therefore, divide 30 by 25%.
30/.25 = $120
The answer should be (exact number- 93/10) (decimal form- 9.3) (mixed number- 9 3/10)
sorry if i’m incorrect
Answer: 
Step-by-step explanation:
88 can be rewritten as 8 x 10 and 8 can be rewritten as 
making a 2 come out of the root.
10 can be rewritten as 2 x 5.
2*2 can also be rewritten as 
making a 2 come out of the root.
We can't keep simplifying the root.
10 x 7 = 70
1 x 7 = 7
9 x 7 = 70 - 7
9 x 7 = 63
