Answer

D.42

Step-by-step explanation:

It's pretty easy and hard at the same time just do not overthink it. Obviously, the bus leaves with R occupants including the driver but that still means that there are occupants, to begin with. Now remembering that 3 people get on each stop you can take it to multiply 3*10  (3 people, ten stops) you would get thirty. Would this be the answer? NO! Remember that you began with R occupants to begin with and either using the process of elimination or common sense you can conclude that 12,24 are improbable answers because they are lower than thirty, and what about thirty? No, because you had thirty people in addition to the original occupants so that eliminates thirty. What's left?

Answer:

  • D. 42

================

<h2>Given</h2>

  • The bus has initially R occupants,
  • At each stop the occupants increase by 3,
  • After 20 stops there are 3 times more occupants than after 4 stops.

<h2>To find</h2>

  • The number of occupants after 10 stops

<h2>Solution</h2>

Let's find out the how many occupants are there after 20 and 4 stops, then compare:

After 20 stops:

  • R + 3*20 =
  • R + 60

After 4 stops:

  • R + 3*4 =
  • R + 12

Compare and solve for R:

  • R + 60 = 3(R + 12)
  • R + 60 = 3R + 36
  • 3R - R = 60 - 36
  • 2R = 24
  • R = 12

We found the number of initial occupants.

Use this  to find the number of occupants after 10 stops:

  • 12 + 3*10 =
  • 12 + 30 =
  • 42

Correct answer choice is D.

The two equations are vertical angles, which mean they are equal.

Set each equation to equal each other and solve for x.


3x-3 = 6(x-10)

Simplify the right side:

3x-3 = 6x-60

Subtract 3x from each side:

-3 = 3x - 60

Add 60 to each side:

57 = 3x

Divide both sides by 3:

x = 57 / 3

x = 19

katrin2010 [14]

Answer: 13 weeks

Step-by-step explanation:

First you have to find 10% of 340.00 which is 28, so each week he saves 28.00 for his bike. To find how many paychecks he has to recieve you divide 340.00 by 28.00, which is 12.1, since there is a decimal place you have to round it up to 13 because it is a little bit more than 12 paychecks. ;)
