If you put brackets around (2+1), your method of working is:
1) 15-4*(2+1)=3
2) 15-4*3=3
3) 15-12=3
You don't need any more brackets, as the BIDMAS (brackets, Indices, division, multiplication, addition, subtraction) rule does the rest of the job for you.
The answer is therefore: 15-4*(2+1)=3

Answer: Choice D) </h3>
More members prefer a beach vacation and ski vacation than an adventure vacation.
======================================================
Explanation:
Let's go through the four answer choices to see which one is true.
- Choice A is false because most members prefer a cruise, as 70+72 = 142 is the largest column sum.
- Choice B is false for the same reasoning as choice A.
- Choice C is false. We have 6+1 = 7 people who prefer adventure and 19+21 = 40 who prefer to ski, giving 7+40 = 47 people who prefer either. But this is nowhere near 142 we found back in choice A above. So more people prefer a cruise than the combined amount for adventure and ski.
- Choice D is true. Adding the column totals for "beach" and "ski" gives (5+6)+(19+21) = 11+40 = 51, and this exceeds the column total of "adventure (6+1 = 7).
Answer:
25%
Step-by-step explanation:
Step one:
A store normally sells certain dress for $160 during a special sale
the store reduces the price of the dress to $120
Step two:
Percent reduction= change in price/initial price *100
Percent reduction= 160-120/160 *100
Percent reduction= 40/160*100
Percent reduction==0.25*100
Percent reduction=25%
