Answer 2

$\text{We need to make an equation to represent the hours she spent working}\\\text{on the second week}\\\\\text{We know she spent a total of 55 hours working}\\\\\text{We also know that she spent 32 hours working on the project}\\\text{in the first week}\\\\\text{Represent x as the second week:}\\\\32+x=55\\\\\text{Solve for x:}\\\\32+x=55\\\\\text{Subtract 32 from both sides}\\\\x=23\\\\\boxed{\text{Zaire spent 23 hours working on the second week}}$
