April scored 78% on her final exam. If each question was worth 4 points and there were 200 possible points on the exam, how many questions did April answer correctly?

April scored 78% on the test meaning she earned 78% of the possible points on the test. There were 200 possible points on the test so she earned 200 x 0.78 = 156 points. Each question is worth 4 points so she got \( \frac{156}{4} \) = 39 questions right.
If the ratio of home fans to visiting fans in a crowd is 4:1 and all 36,000 seats in a stadium are filled, how many home fans are in attendance?
| 26,667 | |
| 35,000 | |
| 28,800 | |
| 31,333 |
A ratio of 4:1 means that there are 4 home fans for every one visiting fan. So, of every 5 fans, 4 are home fans and \( \frac{4}{5} \) of every fan in the stadium is a home fan:
36,000 fans x \( \frac{4}{5} \) = \( \frac{144000}{5} \) = 28,800 fans.

What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 24 | |
| 31 | |
| 29 | |
| 35 |
The equation for this sequence is:
an = an-1 + 2(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
