Answer: 24 and 76
Step-by-step explanation:
{

10
d

q
=
2140
From the first equation, we have
d
=
100
−
q
Substituting that into the second equation, we have
10
(
100
−
q
)

25
q
=

⇒

q

⇒
15
q
=

⇒

=
76
Knowing that
q
=
76
we can substitute that value into the first equation to obtain
d
+
76
=

∴
d
=
24
Thus, Sue has
24
