Q. Muneera is planning a 300 km 300 \mathrm{~km} trip. She wants to write an equation that shows how many hours the trip will take (t) (t) in terms of the rate at which she travels (r) (r) .\newlineHow should Muneera write her equation?\newlineChoose 11 answer:\newline(A) 300t=r \frac{300}{t}=r \newline(B) 300r=t \frac{300}{r}=t \newline(C) 300=rt 300=r t
  1. Calculate Time Formula: Distance=Rate×Time\text{Distance} = \text{Rate} \times \text{Time}, so Time=DistanceRate\text{Time} = \frac{\text{Distance}}{\text{Rate}}.
  2. Substitute Values: Muneera's trip is 300 km300\,\text{km}, so plug that in for Distance.
  3. Solve for Time: Time (tt) is what we're solving for, and rate (rr) is what we'll divide by.
  4. Final Equation: The equation should be t=300rt = \frac{300}{r}.
  5. Correct Equation: Looking at the choices, (B)300r=t(B) \frac{300}{r}=t is the correct equation.

Question
Jill bought a used motorcycle from a seller online for $1,200. The seller will charge her $5 a day to store the motorcycle at his house until she is able to pick it up. You can use a function to describe the total amount of money Jill will owe the seller if she waits xx days to pick up the motorcycle.\newlineWrite an equation for the function. If it is linear, write it in the form g(x)=mx+bg(x) = mx + b. If it is exponential, write it in the form g(x)=a(b)xg(x) = a(b)^x.\newlineg(x)=‾g(x) = \underline{\hspace{3em}}
