Answer:
84.29%
Explanation:
Quarterly tax revenue collected = $70 billion
Thus,
annual tax revenue collected = $70 billion × 4
= $280 billion
Total amount allocated = $15 billion + $29 billion
= $44 billion
Therefore,
Percentage of annual tax revenue allocated
= [ $44 billion ÷ $280 billion ] × 100%
= 15.71%
Hence,
Percentage of its total annual tax revenue is left for allocation to the remaining categories of government spending
= 100% - 15.71%
= 84.29%
