Question

Using the function f (x) = 400 – 15x, where f(x) = the remaining pounds of grain in the truck, and (x) represents the amount of buckets taken out:

Calculate how many buckets it will take until their is 50 pounds of grain remaining.

Answer 1

`{ \tt{f(x) = 400 - 15x}} \\ { \boxed{ \tt{when \: f(x )\: is \: 50}}} \\ 400 - 15x = 50 \\ 15x = 400 - 50 \\ 15x = 350 \\ x = 23.3 \approx23 \: buckets \\ \\ { \underline{ \blue{ \tt{becker \: jnr}}}}`
