Question

can someone help me?

Answer 1

Answer:

You would have 4 nickels and 10 dimes.

4 x 0.05 = 0.20
10 x 0.10 = 100 ($1.00)
$1.00+$0.20=$1.20

Answer 2

Answer: She has 6 nickles and 9 dimes.

Step-by-step explanation:

Let n be the # of nickles. Let d be the # of dimes.

n+d=15

0.05n + 0.1d =1.2

5n+10d=120

5(15-d)+10d=120

75-5d+10d=120

5d=45

d=9

n=15-d

n=15-9

n=6
