Answer:
35 Quarters and 36 Dimes
Step-by-step explanation:
d + q = 71
10 + 25 = 1235
10 x 36 = 360
25 x 35 = 875
360 + 875 = 1235
Answer:
There are 35 quarters and 36 dimes.
Step-by-step explanation
x = the number of quarters
y = the number of dimes
x + y = 71
0.25x + 0.1y = 12.35 ---> multiply this equation by 100
now...
25x + 10y = 1235
x + y = 71 ----> multiply this equation by -25
25x + 10y = 1235
-25x - 25y = -1775
[tex]\frac{-15}{-15} = \frac{-540}{-15}[/tex]
y = 36 dimes
next step
x + y = 71
x + 36 = 71
- 36 - 36
x = 35 quarters
