Question

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

Answer 1

66 nickels = 66 x $0.5 = $3.30

$7.80 - $3.30 = $4.50

$4.50 / $0.10 = 45

Brielle has 45 dimes.

Answer 2

66*0.5=3.30

7.80-3.30=4.50

4.50/0.10=45

ANSWER: 45 dimes
