When planning his crops, Farmer Sue knows that her 15 acres can support apples and pecans. She wants to make $8,500 from her crops. She can make $1,050 per acre of apples (the variable a) and $2,500 per acre of pecans (the variable p). Which equation below would be a constraint in her system of equations?

a)1,050a + 2,500p = 8,500

b)a + p = 15

c)a - p = 15

d)2,500p - 1,050a = 8,500

ok...

    they say that the total Sue expects from her crops is = $8500

 
and
    she gets $1050 per acre from apples...
if she grows "a" acres then her outcome will be
                                  1050a
   
she gets $2500 per acre from pecans
if she grows "p" acres then the outcome will be
                                  2500p

 
but since her total is 8500

          1050a + 2500p = 8500 ----(1)

             21a + 50p = 170 -----(1)

since her land area is 15 acres

                a + p = 15 ----(2)

 
so.. ur choices will contain one out of the followings..

 
hope this will help ya :)
