desmos calculator
10 students (brass)=40% of band
4 students (strings)=16% of band
? students (other)=44% rest of band
14/56%=?/44%
(cross multiply to find ?){don't forget to turn percents into decimals}
?=11
There are 25 students in total in the band.
We define the variables:
x = dimes
y = nickels
z = pennies
We write the system of equations:
0.1x + 0.05y + 0.01z = 1.10
y = 3z
x = z-2
Solving the system of equations we have:
x = 3
y = 15
z = 5
Answer:
The number of nickels and pennies is:
nickels = 15
pennies = 5
