<PRE><B>Question 1202604</B>
We have a jar of coins, all pennies and quarters. All together, we have 191 coins, and the total value of all coins in the jar is $24.23. How many pennies are there in the jar?
$24.23 = 2423 cents

Let there be  p  pennies and  q   quarters

coin count equation

p+q=191...............................................(1)

Money value equation

p+25q= 2423 ......................................(2)


subtract (1) from (2)


24 q= 2232

q = 2232/24

q= 93 quarters

p = 191-93= 98 pennies




98+93*25=  2423
