Question

This table shows the relationship between jars of peanut butter and jars of jelly stocked each week at a camp. The ratio of jars of peanut butter to jars of jelly is constant in each column.

Let p = jars of peanut butter for 35 jars of jelly
Let j = jars of jelly for 42 jars of peanut butter

What is the correct values for p and j?

Answer 1

p=30 j=49

Explanation:

18-6=12

21-7=14

42-12=p p=30

35+14=j j=49

Answer 2

p=30 and j=49

Explanation:

Given:

Is a table which shows the relationship between jars of peanut butter and jars of jelly stocked each week at a camp

p=jars of peanut butter for 35 jars of jelly

j=jars of jelly for 42 jars of peanut butter

From the table we find that from the table we find that

p:j=6:7

Or 7p=6j

Using this we can fill up the missing values

Using the above we find missing value of p as

7p=6(35)

p=30

Similarly when p =42 j is missing

7(42)=6(j)

j=49
