Answer:
the 3rd answer option
Step-by-step explanation:
why ?
similar to the other questions.
we know the total number of coins, which is a sum of quarters and dimes. nothing else is in there.
so,
16 = q + d
and each type of coin has a defined value : a quarter is $0.25, a fine is $0.10.
and so, when you add up the value of all quarters and all dimes you get $3.10.
