Tangerine trees yield 50 pounds of fruit per acre and grapefruit trees yield 75 pounds of fruit per acre. Suppose Josh's farm has t acres of tangerine trees, g acres of grapefruit trees, and yields 1,500 pounds of citrus. What is the constraint equation that represents this scenario?

 50t + 75g = 1,500 75t + 50g = 1,500 125c = 1,500 t + g = 1,500
