Jimmy's score is determined by dividing the number of points he got right by the total number of points, then multiplying times 100. Let x = Jimmy's number of points

$\frac{x}{46}$ $"x"/"46"$ = $0.75$ $"0.75"$ x $100$ $"100"$ Solve for x.

$x$ $"x"$ = $0.75 (46 points)$ $"0.75"("46 points")$ x $100$ $"100"$ = $34.5 points$ $"34.5 points"$

Jimmy got 34.5 points out of 46 points correct.

Check: $\frac{34.5 points}{46 points}$ $"34.5 points"/"46 points"$ x $100$ $"100"$ = $75%$ $"75%"$
