240................................ It had to be 20 characters so sorry for the large answer <span />
AbG is. I tedious angel meajsres of the polygon
X = number of dimes
y = number of quarters
---
10x + 25y = 2565
y = x + 20
---
put the system of linear equations into standard form
---
10x + 25y = 2565
x - y = -20
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = 59
y = 79
Answer: 0.70
Step-by-step explanation the same as decreased by 30%" would be (1.00 - 0.30)(original cost), or 0.70(original cost)
