\mathsf{y = 4^2 + 5(4)}

\mathsf{4^2 = 4 \times 4 = 16}

\mathsf{y = 16 + 5(4)}

\mathsf{5(4) = 20}

\mathsf{y = 16 + 20}

\mathsf{36= 20 + 16}

gregori [183]

Answer:

Step-by-step explanation:

Let c represent the total cost of booking either Uber or Lyft for x miles.

Let m represent the number of miles ridden with either Uber or Lyft.

Uber charges $0.80 per mile and a booking fee of $2.30. This means that the total cost of riding with Uber for m miles would be

c = 2.30 + 0.8m - - - - - - - - - -1

Lyft charges $1.07 per mile with no booking fee. This means that the total cost of riding with Lyft for m miles would be

c = 1.07m - - - - - - - - - -2

Equation 1 and equation 2 are the system of equations that bests models this situation

Ebony's bank balance 1st reached $400 on Day 4. The last day her balance was $400 was Day 8.
Tanya [424]

Ebony’s bank balance is $400 was Day 8 and this can be explained below.

<h3>How to explain the information?</h3>

Jade cannot be true because for every transaction made during withdraws, a little amount of money is collected and as such the amount will never remain $400.

Note that the scenario for the above to occur is:

On day 4, her balance = $400

On day 5, her balance = $40

On day 6, her balance = $400

On day 7, her balance = $400

On day 8, her balance = $400

Another fact is that since she deposited 400 at first, on day 8, there will be a 0 increase so the amount will still be 400.

Therefore, if the above is the case, one can deduce the fact that her balance will still be $400.
