Answer:
d. 25%.
Explanation:
Given the following data;
Tax revenue, T = $320 billion
Education budget, Eb = $80 billion
To find the percentage of the tax revenue spent on education, we would use the formula;
[tex] Percentage = \frac {E_{b}}{T} * 100 [/tex]
Substituting into the formula, we have;
[tex] Percentage = \frac {8,000,000,000}{32,000,000,000} * 100 [/tex]
[tex] Percentage = \frac {1}{4} * 100 [/tex]
Percentage = 25%
