Answer:
B
Step-by-step explanation:
The first week, she worked
[tex]3 \times 2\frac{1}{2} = 3 \times \frac{5}{2} = \frac{15}{2} [/tex]
The second week, she worked
[tex]3 \times 2 \frac{1}{4} = 3 \times \frac{9}{4} = \frac{27}{4} [/tex]
Total number of hours she worked over these 6 days
[tex] \frac{15}{2} + \frac{27}{4} = \frac{57}{4} = 14\frac{1}{4} [/tex]
