When planning his crops, farmer julie knows that her 25 acres can support oranges and pears. she wants to make $7,500 from her crops. she can make $2,050 per acre of oranges (the variable o) and $2,000 per acre of pears (the variable p). which equation below would be a constraint in her system of equations?
2,050o - 2,000p = 7,500
2,050o + 2,000p = 7,500
o - p = 25
o + p = 25
