Answer:
QUESTION 9: 6.06
QUESTION 10: Barbara= 238
Collete= 136
Explanation:
QUESTION 9:
original price= 82500
new price= 77500
decrease in price= 82500-77500
=5000
percentage in decrease= 5000/82500 x 100
=6.06
QUESTION 10:
Adele:Barbara:Collete
9 : 7 : 4
9x : 7x : 4x
total amount they share= 9x + 7x + 4x
= 20x
since they share a total amount of 680, then 20x= 680
dividing both sides by 20 then gives x
so,
x= 680/20
=34
since Adele receives 9x
9(34)
Adele receives 306
since Barbara receives 7x
7(34)
Barbara receives 238
since Collete receives 4x
4(34)
Collete receives 136
hope it helps!
