Which of the following statements are equivalent to the statement "price increased by 100%"? choose all correct answers. (a) the price doubled (b) the price is 150% of the price before (c) the price was reduced by a quarter (d) the price became a half of what it was before (e) the price is now 1.5 of what it was before (f) the price now is 66 2/3% of what it was before (g) the price now is 200% of what it was before (h) the price is 75% of what it was before pl

Answers:
(A) The price doubled
(G) The price now is 200% of what it was before

Explanation:
Assume that the original price of the product is x. Therefore, x represents 100% of the original price.

Now, we are given that:
The price increased by 100%

This means that:
new price = old price + 100% of old price
new price = x + 100% (x) 
new price = 2x
Thus, we can note that the price is doubled

We know that x represents 100% of the price of the product.
Therefore:
new price = x + x = 100% + 100% = 200%
This means that the new price is 200% of the old price

Notes:
Options C,D, F and H are incorrect because they represent a decrease in the price while we know that the price increased
Options B and E are incorrect because they represent an increase of 50% in the price while we know that the increase is 100%

Hope this helps :)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
