A teacher gave a test with 50 questions, each worth the same number of points. Donovan got 39 out of 50 questions right. Marci's score was 84%. How many more questions did Marci answer correctly?

The correct answer is that Marci scored 5 more questions correct than Danovan. It is relatively simple to answer this equation. The first step simply involves figuring out how Donovan did, and to do so you just need to divide his scores (39/50) to get the number 0.78. With this information, we can then work out Marci's score. We know that she scored 88%, which means she must have scored somewhere in the 40s. Once you've figured out the score out of 50, you then just need to divide it as you did with Donovan[s score. You will get to 44/50, which will give you the answer of 0.88.

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
