35n=280
n=8 8 dimes and 8 quarters
we know that
Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph
So

in this problem

substitute the values in the formula above

Divide by
both numerator and denominator

therefore
the answer is

TV = VX.
3x-24 = 2x + 1
Add 24 to both sides:
3x = 2x + 25
Subtract 2x from both sides:
X = 24
VX = 2(25) + 1 = 50 + 1 = 51
The answer is 51
