Question 1114732
Sunita has a coin collection of dimes, quarters, and silver dollars. 
The number of quarters is 5 less then three-fourths of the number of dimes.
q = (3/4)d - 5
The number of silver dollars is 7 more than five-eighths of the number of dimes.
s = (5/8)d+7
There are 116 coins in all.
s + q + d = 116
--------------------------
Substitute for "q" and "s"  and solve for "d"::
(5/8)d+7 + (3/4)d - 5 + d = 116
(5/8)d+7 + (6/8)d + d = 121
-------------------------------
(11/8)d = 114
d = 82.9
Note:: The number of dimes must be a whole number, not 82.9.
------------

How many dimes, quarters, and silver dollars does Sunita have?
