1.

The knitting club sold 40 scarves and hats at a winter festival and made $700 from the sales. They charged $18 for each scarf and $14 for each hat.
If s represents the number of scarves sold and h represents the number of hats sold, which system of equations represents the constraints in this situation?

40 s + h = 700 and18 s + 14 h = 700

18 s + 14 h = 40 and s + h = 700

s + h = 40 and 18 s + 14 h = 700

40 ( s + h ) = 700 and 18 s = 14 h
