You have 22 dimes and 11 pennies.
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:-)
You have 22 dimes and 11 pennies.
The X.X1 at the end of the number implies that there could be 1, 11, 21, 31, etc. pennies. Now, we could go through and test the instances. .01 means that there is 1 penny. Therefore, there are 2 dimes to make .31, which does not work. .11 means that there are 11 pennies. Therefore, 22 dimes are required, which make $2.31. This works, so there are 22 dimes.
There are fifteen (15) nickels.
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 6 dimes
10 dimes 5 quarters
You need to define variables for the different types of coins, write the corresponding equations, then solve them. One equation for each fact. Here are the equations:5N + 10D + 25Q = 1250 D = 2N Q = 2D
Helen has twice as many dimes as nickels and five more quarters than nickels the value of her coins is 4.75 how many dimes does she have?
Let N be the number of nickels. The value of nickels is 0.05N and the value of dimes is 0.10(2N-12). We can form the equation 0.05N + 0.10(2N-12) = 2.55 and solve for N. After solving, we find that there are 9 nickels.
12 quarters and 6 dimes 2(.25x) + .10x = 3.60 50x + 10x = 360 60x = 360 x = 6
7 quarters 2 dimes 4 nickels
