Fiona bought some socks that cost $4.95 for each pair and some belts that cost $6.55 each. Fiona spent $27.95 in all. Let a represent the number of pairs of socks purchased and b the number of belts purchased.
Which equation models the situation?
a + b = 11.50
a + b = 27.95
4.95a + 6.55b = 27.95
6.55a + 4.95b = 27.95
