Question 521287
There a bus leave the interchange.
Let x = original no. of passengers as the interchange
:
Write an EXPRESSION for each statement:
:
 at the bus stop 1/4 passengers alighted and 12 passengers boarded,
x - {{{1/4}}}x + 12
simplifies to
{{{3/4}}}x + 12
:
at the next bus stop 1/2 passengers alighted and 13 passengers boarded.
{{{1/2}}}[{{{3/4}}}x+12] + 13
{{{3/8}}}x + 6 + 13
{{{3/8}}}x + 19
:
 At the final stop there were 25 passengers alighted the bus.
{{{3/8}}}x + 19 - 25 = 0
{{{3/8}}}x -6 = 0
{{{3/8}}}x = 6
3x = 8(6)
3x = 48
x = 48/3
x = 16 passengers first when bus leaves the interchange ?
