Answer:
90 coins
Step-by-step explanation:
Nickels = .05
Quarters = .25
half dollars = .50
Since you have an equal number of them, call that x
.05x+.25x+.50x = 24
Combine like terms
.80x = 24
Divide by .8
.80x/.8 = 24/.8
x =30
You have 30 nickes, 30 quarters and 30 half dollars
The total number of coins is
30+30+30 = 90 coins
The biggest common factor number is the GCF number. So the greatest common factor 72 and 80 is 8
It is exponential
Cost = 2.49 * y
You really should spend the time. Math is used everywhere.
