Given:
Total number of coins (Quarters and dimes) = 60
Total amount = $12.45
To find:
The number of quarters and dimes.
Solution:
Let x be the number of quarters and y be the number of dimes.
We know that,
1 quarter = 0.25 dollar
1 dime = 0.10 dollar
Total coins:
...(i)
Total amount:
...(ii)
From (i), we get
...(iii)
Putting this value in (ii), we get




Divide both sides by 0.15.


Putting x=43 in (iii), we get


So, the number of quarters is 43 and the number of dimes is 17.
Therefore, the correct option is b.
You would do 3.5 * 16 = $56
Your answer is A. $56

So what she wrote down is zx2x4 but you can simplify that to zx8 which then can be simplified to 8z. Which is the answer
Hmmm anyhow, removed this one, since it had a couple of mistakes
but ... tried it, and didn't come up with much, which leads to think, that
the expressions are off a bit
anyhow, if you have an exponential expression, shoot it
