Answer 1

Here's what I get

Explanation:

`\begin{array}{cccc}\bf{Week}& \textbf{Earned/Spent} & \textbf{Change} & \textbf{Net Change}\\1 & \text{Earned \$80} & + 80 & + 80\\2 & \text{Spent \$85} & \mathbf{- 85} &\mathbf{-5}\\\end{array}`

The net chance in Jacob's savings was +80 in the first week, -85 in the second week, and -5 overall.
