The coins in the store's cash register total $12.50. The cash register contains only nickels, dimes, and quarters. There are twice as many dimes as nickels. There are also twice as many quarters as dimes. How many quarters are in the cash register?
12 quarters and 6 dimes 2(.25x) + .10x = 3.60 50x + 10x = 360 60x = 360 x = 6
7 quarters 2 dimes 4 nickels
16 nickels, 8 dimes, 4 quarters. 25+25+25+25+10+10+10+10+10+10+10+10+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5= 260
I believe 1 billion pennies are equal to $10,000. I just added in my head so the answer may be wrong.1,000,000,000 pennies divided by 100 = 10,000,000 The first conclusion ($10,000) seems to be missing a few zeros.1 Billion (1,000,000,000) divided by 100 (to make it dollars) drops two zeros off the total, so instead of nine zeros you would have seven zeros (10,000,000). So, 10 million dollars. I would happily pay you TWICE ten thousand dollars for one billion of your pennies:-)
