To find how much Chris originally saved, we need to solve the equation:
[tex]\[
\frac{1}{2} x + 20 = 60
\][/tex]
Here’s the step-by-step solution:
1. Isolate the term involving [tex]\(x\)[/tex]:
- Subtract 20 from both sides of the equation.
[tex]\[
\frac{1}{2} x + 20 - 20 = 60 - 20
\][/tex]
Simplify both sides:
[tex]\[
\frac{1}{2} x = 40
\][/tex]
2. Solve for [tex]\(x\)[/tex]:
- To eliminate the fraction, multiply both sides of the equation by 2.
[tex]\[
2 \cdot \frac{1}{2} x = 2 \cdot 40
\][/tex]
Simplify both sides:
[tex]\[
x = 80
\][/tex]
So, Chris originally saved [tex]\(\$ 80\)[/tex]. Therefore, the correct answer is:
[tex]\[
\boxed{80}
\][/tex]
