Step-by-step explanation:
<u>Answer-</u>
<em>The value of y is
when x=7 and z=4.</em>
<u>Solution-</u>
As given in the question, y is directly proportional to x, so
-----------------1
And also y is directly proportional to z, so
-----------------2
Combining equation 1 and 2,

Where,
k = proportionality constant
When x=6 and z=1, y=4. Putting theses values,




Now, we have to find the value of y, when x=7 and z=4


Therefore, the value of y is
when x=7 and z=4.
The answer would be about 65%. To find this you would take the number of square table cloths and divide it by the total. So you would do 55/84=0.654. I hope this helps :)
