Wendy found a small jar with pennies and counted them all and then challenged her brothe craig to guess how many pennie she had. she gave him some clues to out the number of pennies is between 70 and 100.(you can divide the pennies in to groups of 5.) if you divide the pennies into groups of 4,there will be 3 left over. if you divide the pennies into groups of 6 or 9,there will be 5 left over. if you divide the pennies into groups of 10,there will be 5 left over. how many pennies are in a jar?
