johny has a coin collection. he has 98 coins in all. he has 3 times as many pennies as dimes. he has 4 more dimes than nickles, and 6 less dimes than quarters.
Read the given information and take a bit of time to find a way to write expressions for the numbers of pennies, nickels, dimes, and quarters as easily as possible using a single variable.
The number of pennies is 3 times the number of dimes: x = number of dimes; 3x = number of pennies.
He has 4 more dimes than nickels, so the number of nickels is 4 less than the number of dimes: x-4 = number of nickels.
He has 6 fewer dimes than quarters, so the number of quarters is 6 more than the number of dimes: x+6 = number of quarters.
Now that you have expressions in terms of a single variable for the numbers of each coin, write and solve the equation that says the total number of coins is 98:
I'll let you finish from there....
