Problema Solution
A charity organization is collecting change to raise money. They have collected twice as many dimes as quarters, 22 more nickels than dimes, and 3 times as many pennies as nickels. Define a variable for the number of quarters collected.
Answer provided by our tutors
let 'q' represent the number of quarters, then '2q' represents the number of dimes, '2q+22' represents the number of nickels and '3(2q+22)' represents the number of pennies
this definition uses 'q' for the number of quarters collected
let 'T' represent to total donations in dollars, then solving the following equation will calculate the number of quarters collected:
T = 0.25q + 0.1(2q) + 0.05(2q+22) + 0.01(3(2q+22))
