C. 12 nickels and 9 dimes.
This is the only one that adds up to 1.50
A 25 NICKLES 100 DIMES
Step-by-step explanation:
I believe 12 nickels and 9 dimes
Sam has 5 dimes and 7 nickles
Option D
There are 15 dimes and 5 nickels
Solution:
Let "d" be the number of dimes
Let "n" be the number of nickels
We know that,
Value of 1 dime = $ 0.10
Value of 1 nickel = $ 0.05
There are three times more dimes than nickels
Therefore,
Number of dimes = 3(number of nickels)
d = 3n ---------- eqn 1
The total value is $ 1.75
Therefore, we frame a equation as:
Number of dimes x Value of 1 dime + number of nickels x Value of 1 nickel = 1.75
[tex]d \times 0.10 + n \times 0.05 = 1.75[/tex]
0.10d + 0.05n = 1.75 -------- eqn 2
Substitute eqn 1 in eqn 2
0.10(3n) + 0.05n = 1.75
0.3n + 0.05n = 1.75
0.35n = 1.75
n = 5
Substitute n = 5 in eqn 1
d = 5(3)
d = 15
Thus there are 15 dimes and 5 nickels
answer: no 98
step-by-step explanation:
Answer C is the correct choice
There are 9 nickels and 63 dimes.
Step-by-step explanation:
Let x be the number of nickels. There are 7 times as many dimes as nickels, so there are 7x dimes.
Amount in dimes [tex]=7x\cdot 10=70x[/tex] cents
Amount in nickels [tex]=x\cdot 5=5x[/tex] cents
The value of dimes is $5.85 more than the value of the nickels, so
[tex]70x-5x=585[/tex]
Solve this equation
[tex]70x-5x=585\\ \\65x=585\\ \\x=\dfrac{585}{65}\\ \\x=9[/tex]
There are 9 nickels and 63 dimes.
