Question

At the beginning of the school year, teachers
have 240,000 sheets of copier paper to use. If
about 2,000 sheets of paper are used each day
during a school year, which equation best
describes s, the number of sheets that are left
after d days of school? Write the linear model
in slope-intercept form.

Answer 1

Answer:

$s=-2000d+240000$

Step-by-step explanation:

Given:

Initial number of sheets, $s_{o}=240000$

Sheets used per day = 2000

∴ Sheets used in $d$ days, $s_{d}=2000d$

Therefore, sheets left after $d$ days is given as:

$s=s_{o}-s_{d}\\s=240000-2000d\\s=-2000d+240000$

Therefore, the number of sheets that are left after $d$ days of school in slope-intercept form is $s=-2000d+240000$, where, slope is -2000 and y-intercept is 240000.
