Answer:
No, David's answer does not seem reasonable.
Let x= original purchase amount
25x = $10.25, so solve for x by dividing both sides by .25, and you get x = $41.

Answer:
2-9=x
HOW
let the number be x
then 2 less than product 9
so
2-9
and a number
we don,t know number so take it x
so 2-9=x
F(x) = x^2 + 1
f(4) = 4^2 + 1 = 16 + 1 = 17
2*f(4) = 2 * 16 = 32
