Final answer:
Tyrone spends 6% of his monthly budget on car expenses (Option 3).
Step-by-step explanation:
To find the percentage of Tyrone's monthly budget that he spends on car expenses, we can look at the pie chart. Let's assume that the portion representing car expenses is x%. We know that the sum of all the percentages in the pie chart is 100%. So, if we subtract the percentages of the other expenses from 100%, we should get x%.
From the pie chart, we can see that the percentages of the other expenses are 30%, 25%, 15%, and 19%. Subtracting these values from 100%, we get 6%. Therefore, Tyrone spends 6% of his monthly budget on car expenses, which corresponds to option 3) 6%.
