If P(x) = 25x² - 24x + 615
Then, when x = 8:
P(x) = P(8)
= 25(8)² - 24(8) + 615
= 1600 - 192 + 615
= 2023
Let number of one rupee coins be x
Let number of two rupee coins be 2x
=> 2x+x=30
=>3x=30
=> x = 10
Hence , number of one rupee coints are x = 10
Number of 2 rupee coins are 2x = 2(10) = 20
Hope this helps you dear:)
Have a good day!
