Answer: 2x + 3y = 35
Explanation:
Let x = number of daisies
Let y = number of tulips
Since one sister likes daises which costs $2.00 per stem and the other likes tulips which costs $3.00 per stem, the inequality that could be use to determine how many of each flower he could buy if he only has $35.00 to spend will be:
2x + 3y = 35
