The price of a calculator has decreased from $200 to $150. what is the percentage of decrease?
a) 3%
b) 25%
c) 33%
eliminate
d) 50%

The answer is B) 25%

Step-by-step explanation:

If half of 200 is 100 (50%) and you're trying to find out what $150 is equal to from the decrease rate, you divide 50 in half because you're finding the percentage of $200 to $150 and there's not much of a difference, so 25% is the correct answer.

the discriminant is 64 + 4*1*12 = 112

this is prime.
