Brielle's piggy bank has all nickels and dimes. The total value of the money in her piggy bank is $7.80. If Brielle has 66 nickels, write and solve a linear equation to find the number of dimes she
has.
What’s the linear equation

Step-by-step explanation:

7.80=66(.05)+.10(x)

7.80=3.30+.10(x)

7.80=3.30+.10x

4.50=.10x

x=45

66 nickels at .05=3.30

45 dimes at .10= 4.50

3.30+4.50= 7.80

your answer is b ^w^ hope i
