Answer 2

Answer:

B. 12 1/2 CUPS

Step-by-step explanation:

$1 \:dough = 2\frac{1}{2} \:cups\:of\:flour\\5 \:batches=x$

Cross multiply

$x = 5\times 2\frac{1}{2} \\\\2\frac{1}{2}=\frac{2\times 2+1}{2}\\\\x=5\times \frac{5}{2}\\\\x=\frac{5\times \:5}{1\times \:2}\\\\x=\frac{25}{2}\\\\x=12\frac{1}{2}\:cups$
