Problema Solution
Juwan has a change jar that contains only nickels and half dollars. He has 92 coins which add up to a total of $24.40. How many of each type of coin does he have?
Juwan has_____nickels.
Juwan has_____half dollars.
Answer provided by our tutors
let 'x' represent the number of nickels, then '92-x' represents the number of half dollars
24.40 = 0.05x + 0.50(92-x)
solving for 'x' we have x=48
92-48 = 44
Juwan has 48 nickels and 44 half dollars
