Question

A farm receives a delivery of 300 bales of hay. The farmer can unload the bales of hay at a rate of 90 bales per hour. Which function, f(t), represents the number of bales of hay that still need to be unloaded after t hours? f(t)=300(t−90) f(t)=300−90t f(t)=300(t+90) f(t)=300+90t

Answer 1

Answer:

$f(t)=300-90t$

Step-by-step explanation:

Number of bales to be delivered = 300

Hourly rate to unload bales  = 90

Let number of hours be represented by 't'.

Also$f(t)$ represents the number of bales that still need to be unloaded after 't' hours.

The number of bales that still need to be unloaded after t hours can be calculated by Subtracting rate to unload bales multiplied with number of hours from Number of bales to be delivered.

framing in equation form we get;

$f(t)= 300-90t$

Hence Final Answer is $f(t)= 300-90t$.
