question:

which of the following statements are equivalent to the statement "price increased by 1/2 "?

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

Step-by-step explanation:

If the price increased by 1/2, it means that means that it is 150% of what it was before because 100% + 50 = 150%. B is correct. 1.5 is just another way of saying the same thing, just in decimal form, so e is also correct.
