Answer:
9
Step-by-step explanation:
14
Arranging the numbers in ascending order,
9,11,11,12,13,13,14,14,17,17,18,19,22,23,25
Median = 14
Grapes=19.51
Apples=$2.19 per pound
Grapes=$2.60 per pound
Apples+Grapes=20 pounds
A+G=20
A=20-G
Equation is
PaA+PgG=35.80
2.19A+2.60G=35.80
2.19(20-G)+2.60G=35.80
43.8-2.19G+2.60G=35.80
43.8-0.41G=35.80
-0.41G=35.80-43.8
-0.41G=-8
Divide both sides by 0.41
G=19.51 pounds
Recall
A=20-19.51
A=0.49 pounds
x=13,y=39
y=3x,x+y=52
x+3x=52
4x=52
x=52/4
x=13
y=3(13)
y=39
