A parking meter contains dimesdimes and quartersquarters worth $8.05. There are 52 coins in all. Find how many of each there are
Answer provided by our tutors
Let 'd' represent the number of dimes, then '52-d' represents the number of quarters. Each dime is 0.1d and each quarter is 0.25(52-d):
8.05=0.1d+0.25(52-d)
d=33
52-33=19
So 33 dimes and 19 quarters were in the parking meter.
