Cartridge resource calculation

Question

Fintech

Given:
Cartridge yield 15,000 pages at 5% coverage.

Challenge:
What is the cartridge yield at 8% coverage?

=)

Answer 1

9375 sheets.

Answer 2

Mathematically, this is a problem for mushrooms / berries with different humidity :)
Google it, this is grade 7.
And it is solved like this:
5% coverage - x
8% coverage - y
0.05x=0.08y
y = x / 1.6
y = 9375
- You can think differently: from 5 to 8, ink consumption increases by 60%. Consequently, the production of sheets will fall by the same amount.

Answer 3

A thousand apologies, where did 1.6 come from?

0.05x=0.08y
0.08y=0.05x
y=0.05/ 0.08x y
=1/ 1.6x
y=x/1.6
or an increase of 60%, i.e. an increase of 1.6 times.
Consequently, the print resource in sheets will decrease by 1.6 times.

I completely forgot about math.

it happens (:
