Given : Candela has $5.60 in quarters and dimes in her pocket.
There are 35 coins total,
To Find : how many of each does she have
Solution:
Quarter value = 0.25 $
Dime value = 0.1 $
Let say Quarters = Q
Dimes = 35 - Q
Value of Quarters = 0.25Q
Value of Dime = 0.1(35 - Q) = 3.5 - 0.1Q
0.25Q + 3.5 - 0.1Q = 5.6
=> 0.15Q = 2.1
=> Q = 14
Quarters = 14
Dimes = 35 - 14 = 21
