To find 50 percent, you multiply the number by 0.5 (for 30%, 0.3 etc.).
42.88 * 0.5 = 21.44
Percent error = (estimate - real)/(real) * 100
percent error = (78.25 - 75.50)/(75.50) * 100
percent error = 3.6%
Well you see here, you need to take attest pre-calculus to answer this question. I am in 6th grade.
