Let 'x' represent the number of baskets and let 'y' be the total cost.
Since the paint costs 14.50 and each basket cost 7.25, then we have the following function:
![y=7.25x+14.50](https://img.qammunity.org/2023/formulas/mathematics/college/4lnt9ppkveixx6aeeuvoqtg6e1lpnusbzx.png)
To find the cost of 4 baskets, we can make x = 4 and solve for y:
![\begin{gathered} x=4 \\ \Rightarrow y=7.25(4)+14.50=29+14.50=43.50 \\ y=43.50 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/8f1bekl0m107ymu2sp9b1vzl33ctkdegsd.png)
therefore, the cost of painting 4 baskets is $43.50
