WHAT IS MISSING? You have dimes and nickels in your pocket
with a total value of $0.95. There are more dimes than nickels.
How many of each coin do you have?
a. Do you have enough information to write a system of equations
to answer the question?
No for you could only write one equation
$0.10d + $0.05n = $0.95
which would amount to
10d + 5n = 95
which can be divided through by 5 to give
2d + n = 19
But that's just ONE equation. So the answer is no, because
when you have two unknown quantities you must have 2 equations.
But here you only have one.
>>If not, what else do you need to know?<<
You would need to know either
1. the total number of coins
or else
2. How many more dimes you have than nickels.
>>b. Find one possible solution.<<
Here are three possible solutions:
1. 1 nickel and 9 dimes.
2. 3 nickels and 8 dimes.
3. 5 nickels and 7 dimes.
