Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the numbe
r of nickels in the collection?
ANSWER- 0.1(175-n)+0.05n=13.30
2 answers:
N+d=175, so d=175-n
0.05n+0.1d=13.30 now using d found above in this equation yields:
0.05n+0.1(175-n)=13.30
...
1.5(4-g)+1g=5.5
6-1.5g+g=5.5
6-0.5g=5.5
-0.5g=-0.5
g=1
5.5/4=1.375
So your grid should be:
3oz 1.50 4.50
1oz 1.00 1.00
4oz 1.375 5.50
Answer:
The equation we can use is 0.1(175-n)+0.05 n=13.30
Step-by-step explanation:
Number of Dimes= d
Number of Nickels= n
n+d=175, so d=175-n
The value of the dime is $0.10 and the value of each nickel is $0.05 and the whole collection is worth $13.30, so
0.1 d+0.05 n=13.30
Replacing
0.1(175-n)+0.05 n=13.30 this is the equation we have to use to get the number of nickels.
