Answer:
c.
Step-by-step explanation:
Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.
We have $34x + $31.5(17 - x) = $558.
$34x + $31.5(17 - x) = $558
$34x + $535.5 - $31.5x = $558
$2.5x = $22.5
x = 9
Hence the answer is c.
Divide 2.88 by 0.09
2.88/0.09 = 32
$2.88 is 9% of $32
Answer:

Answer:
Therefore no of apples in that group is 18
Step-by-step explanation:
Given:
No. of apples = 36
No. of pears = 20
Also it is given that grocer arranges the fruit into groups that have the same ratio of apples to pears as the whole collection of fruit.
first we find the ratio of apples and pears in whole collection which is given below
No. of apples/No. of pears = 36/20 = 9/5
Now its a problem of ratio
It is given that no of pear in one group is 10
Let the no of apples in that group be X
According to the question
No. of apples in whole collection/ No. of pear in whole collection = No. of apples in the group/ No. of pears in the group -------------> A
9/5 =X/10
=> X = (9*10)/5 = 18
Therefore no of apples in that group is 18.
