-------------------------------------------------
Lily has a piggy bank with 100 coins in dimes in pennies she has a total of $7.57 in the piggy bank
-----------------------------------------------
1 dime is 0.10 dollar.
1 penny is 0.01 dollar.
Multiply the money equation, both sides, by 100 to eliminate the fractions or denominators.
You may want to use elimination first to directly solve for d.
