Answer: 24 and 76 
Step-by-step explanation:
{
d
+
q
=
100
10
d
+
25
q
=
2140
From the first equation, we have  
d
=
100
−
q
Substituting that into the second equation, we have
10
(
100
−
q
)
+
25
q
=
2140
⇒
1000
−
10
q
+
25
q
=
2140
⇒
15
q
=
1140
⇒
q
=
1140
15
=
76
Knowing that  
q
=
76
 we can substitute that value into the first equation to obtain
d
+
76
=
100
∴
d
=
24
Thus, Sue has  
24
 dimes and  
76
 quarters.
