Question

Hanna shops for socks that cost $2.99 for each pair and blouses that cost $12.99 each. Let x represent the number of pairs of socks purchased, and let y represent the number of blouses purchased. Which equation models the purchases she made with $43.92?

x + y = 15.98
x + y = 43.92
43.92x - 2.99y = 12.99
2.99x + 12.99y = 43.92

Answer 1

Cost equals price times quantity, so 2.99x + 12.99y = 43.92.
