Step-by-step explanation:
Answer: 2 bookcases.
Step-by-step explanation:
Let be "x" the number of bookcases that the custodian will be able to repaint completly with 5 gallons of paint.
According to the data given, the custodian needs 2 gallons of paint to repaint one bookcase. Since all the bookcases are equal, you can set up the following proportion:
![\frac{2}{1}=\frac{5}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B1%7D%3D%5Cfrac%7B5%7D%7Bx%7D)
Now you must solve for "x" in order to find its value:
![(x)(\frac{2}{1})=5\\\\2x=5\\\\x=\frac{5}{2}\\\\x=2.5](https://tex.z-dn.net/?f=%28x%29%28%5Cfrac%7B2%7D%7B1%7D%29%3D5%5C%5C%5C%5C2x%3D5%5C%5C%5C%5Cx%3D%5Cfrac%7B5%7D%7B2%7D%5C%5C%5C%5Cx%3D2.5)
Notice that the custodian will be able to repaint 2 bookcases completely, then you can say that:
