If 100 pencils can be sold for $90, then how many pencils are needed to earn $8500?
ira [324]

Step-by-step explanation:

You can set up a proportion.

Let x be the number of pencils needed.

\frac{100}{90} = \frac{x}{8500}

Solve for x.

x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)

bear in mind that, direct proportional equations have a y-intercept.

for y = kx, is pretty much y = kx + 0, where 0 = y-intercept.

and the "k" constant of proportionality, is pretty much just its slope.
