Answer:
Let d represents the dimes and q represents the quarters.
As per the statement:
A piggy bank at the flea market has 5 more than double the number of Dimes than quarters.
⇒q = 2d +5 ......[1]
It is also given that: The money in the piggy bank is worth $7.70.
⇒ ......[2]
Substitute equation [1] into [2] we have;
Combine like terms;
Subtract 5 from both sides we get;
Divide both sides by 3 we get;
Substitute the values of d in equation in [1] we get;
q = 2(0.90) +5 = 1.80 + 5 = $6.80
Therefore, the dimes and quarters are in the piggy bank is $0.90 and $6.80
