Question 1200041
<font color=black size=3>
Answers:
<font color=red>7 nickels and 11 dimes</font>



Work Shown:
n = number of nickels
n+4 = number of dimes


5n = value of the nickels (cents)
10(n+4) = 10n+40 = value of the dimes (cents)
5n+(10n+40) = 15n+40 = total value (cents)


total value = 145 cents
15n+40 = 145
15n = 145-40
15n = 105
n = 105/15
n = <font color=red>7 nickels</font>
n+4 = 7+4 = <font color=red>11 dimes</font>


Check:
7 nickels = 7*5 = 35 cents
11 dimes = 11*10 = 110 cents
7 nickels + 11 dimes = 35 cents + 110 cents = 145 cents
The answers are confirmed.


Side note: 145 cents = 145/100 = $1.45
