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? a. {40s+h=700 18s+14h=700} b. {18s+14h=40 s+h=700} c. {s+h=40 18s+14h=700} d. {40(s+h)=700 18s=14h}
