Question

Write a real-world problem in which you would use the function rule y=20x. (7 -3) x 5 = 4 x ??r=1219369525?

Answer 1

Hey,

A baseball bat has a total cost, price plus tax, of $20.00.  Write a function to calculate the total price of "x" number of bats.

The function would be f(x) = 20x or y = 20x.  For any number, x, of bats purchased, y will give the cost.  This graph will demonstrate the cost function.

I'm not sure about the r=1219369525.

If you need more help, just add more info.
