Answer:
B 4
Step-by-step explanation:
She bought 2 jackets
Jackets = 2*49 = 98
She bought 3 sweaters
Sweaters = 3 * 25 = 75
The costs for the jackets and sweaters is 98+75 =173
She spent a total of 185
185-173 = 12
She spent 12 dollars on socks
Socks are 3 dollars each
12/3 = 4
She bought 4 pairs of socks
