The correct selling price is about $20, and the likely mistake was the manager multiplied the $12 by .67 (the 67%), got about 8, and took that as the price instead of adding it to the original 12, which is what they were supposed to do.
Answer:
-3n ≤ 15
Step-by-step explanation:
"No more than 15" means the number can be less than 15 or equal to 15, but it can't be more than 15.
"The product of -3 and a number" "is no more than" "15".
-3n ≤ 15
-3n ≤ 15
Answer:
x=4 (solution) x=-14 (extraneous solution )
Step-by-step explanation:
|x+5|=9 -------original equation
Equation can be equal to +9 and -9
x+5 =9 x+5 =-9
x= 9-5 x=-9-5
x=4 (solution) x=-14 (extraneous solution )
for checking
x+5 = 9 x + 5=9
4+5= 9 -14+5=9
9=9 -9=-9
Answer:
b<-35
Step-by-step explanation:
b/5-34<-41
b/5<-41+34
b/5<-7
b<-7*5
b<-35
First you find the median, the middle term (if there are an even number of terms it is the average of the middle two terms.) Since you have 21 terms, odd, you just use the middle term, in this case 8. The first quartile works the same way, but just on the left half between the start and the median...so the first quartile is 6.
