Answer:
Let
x
=
x= the number of cups of granola and
y
=
y= the number of cups of raisins.
At the beginning we have
x
=
0
x=0 cups of granola and
y
=
0
y=0 cups of raisins.
We have the direct proportion
y
=
m
x
,
x
≥
0.
y=mx,x≥0.
Given that a recipe calls for
y
=
1
y=1 cup of raisins for every
x
=
2
x=2 cups of granola
1
=
m
(
2
)
=
>
m
=
1
2
1=m(2)=>m=
2

)
(y) and granola
