Question

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?

Answer 1

i know it is p+a=8,500

Answer 2

but do we put the 15 with any of them

Answer 3

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 :)
