Roger loaned Bob $1,300 at an annual interest rate of 3%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $9 | |
| $27 | |
| $8 | |
| $39 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $1,300
i = 0.03 x $1,300
i = $39

What is the next number in this sequence: 1, 4, 10, 19, 31, __________ ?
| 39 | |
| 46 | |
| 51 | |
| 55 |
The equation for this sequence is:
an = an-1 + 3(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 + 3(6 - 1)
a6 = 31 + 3(5)
a6 = 46
What is the next number in this sequence: 1, 4, 7, 10, 13, __________ ?
| 24 | |
| 12 | |
| 22 | |
| 16 |
The equation for this sequence is:
an = an-1 + 3
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 + 3
a6 = 13 + 3
a6 = 16
A bread recipe calls for 2\(\frac{1}{8}\) cups of flour. If you only have \(\frac{1}{4}\) cup, how much more flour is needed?
| 1\(\frac{7}{8}\) cups | |
| 1\(\frac{1}{2}\) cups | |
| 2 cups | |
| 2\(\frac{1}{2}\) cups |
The amount of flour you need is (2\(\frac{1}{8}\) - \(\frac{1}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{17}{8} \) - \( \frac{2}{8} \)) cups
\( \frac{15}{8} \) cups
1\(\frac{7}{8}\) cups
