Quarters = x
dimes = 196 - x
10(196 - x) + 25x = 3940
1960 - 10x +25x = 3940
1960 + 15x = 3940
15x = 1980
x = 132
169 - 132 = 64
Therefor there are 132 quarters and 64 dimes

Answer:
The final amount is 550.93.
Step-by-step explanation:
Here, the given amount is 468.
Now 8% of the given amount is 
⇒ 8% of 468 = 37.44
So, the New amount = Initial Amount + 8% increase
= 468. + 37.44 = 505.44
Now 9 % of the new amount 505.44 is
[tex]\frac{9}{100} \times 505.44 = 45.4896/tex]
⇒ 9% of 505.44 = 45.4896
So, the Final amount = New Amount + 9% increase
= 505.44 + 45.4896 = 550.93
Hence, final amount is 550.93.
Answer:
37 and -18
Step-by-step explanation:
Let one number be x and other y
1 x + 1 y = 19 .............1
1 x -1 y = 55 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by 1
1 x 1 y = 19
1 x + -1 y = 55
Add the two equations
2 x = 74
/ 2
x = 37
plug value of x in (1)
1 x + 1 y = 19
37 + 1 y = 19
1 y = 19 -37
1 y = -18
y = -18
37 and -18
