Jessica is making matching book bags for her 4 friends. Each book bag needs $1\frac{7}{8}$ yards of fabric. Which of the fabrics shown in the table can Jessica use to make all the book bags for her friends?
Explanation
Total fabric needed: $4 \times 1\frac{7}{8} = 4 \times 1.875 = 7.5$ yards. Moons and Stars (7.5), Stripes ($7\frac{3}{5} = 7.6$), and Tie-Dye (7.9) are all $\ge 7.5$.

Solve the following exercise and simplify it to its simplest form: $\frac{2}{5}(-3.75)$
Explanation
$\frac{2}{5} \times (-3.75) = 0.4 \times (-3.75) = -1.5$. The simplest fraction form is $-\frac{3}{2}$.

The table shows the change in the value of Rudo's stocks one day. The next day, the value of the All-Plus stock dropped $\frac{1}{4}$ of the amount it changed from the previous day. What was the total change in the All-Plus stock? Round to the nearest cent.
Explanation
Initial change: -2.50. New drop: $\frac{1}{4} \times (-2.50) = -0.625$. Total change: $-2.50 + (-0.625) = -3.125 \approx -3.13$.

Solve the following exercise and simplify it to its simplest form: $-5\frac{1}{4} \div \frac{7}{8}$
The change in the total amount of Suki's allowance balance over the course of four weeks is shown in the table. Based on the average change in her allowance balance per week, how much money can Suki expect to save or spend over the course of a year?
Explanation
Total 4-week change: 17.55. Average weekly: 17.55 / 4 = 4.3875. Yearly (52 weeks): 4.3875 × 52 = 228.15. Since positive, she saves.
