-2 < x ≤ 1

400

Alicia purchased H half-gallons of ice cream for $3.50 each and P packages of ice cream cones for $2.50 each.  She purchased 14 items and spent $43.00.  What is the system of equations that could be used to solve for the quantity of each item Alicia purchased?

3.50H + 2.50P = 43

H + P = 14
