Answer:
is the required relationship.
Explanation:
We have bee give that the Yusuf earned a total of $180 from drying 12 identically-price pictures at a festival.
That means if we count earning for one picture is:
![(180)/(12)=15](https://img.qammunity.org/2020/formulas/mathematics/middle-school/k63ibc3rnmdc3ed8fpdflyi270ayglgc5s.png)
We need to find the relationship between P and E
Where, P is the price of the picture
And E is the earning.
![E=15P](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zr0rdwybqc13not0wg4kcugm0jgfu3kgkf.png)
If we put different values of P we will get the earning for the number of pictures.
