Answer :
The plumber has enough handles to install the entire 9 sinks
How to calculate the amount of handles needed for installation ?
A plumber needs to install handles in 9 sinks
Each sink has a hot water handle and a cold water handle, that means each sink will require 2 handles. This means the multiplication of 9 and 2
= 9 × 2
= 18
The plumber has a total of 19 handles and 18 handles are required for the installation. This means that he has enough handles and he will be left with one handle.
Hence, there will be enough handles for the installation.
