Question 888142
Let {{{ C }}} = Cost total number of programs printed
Let {{{ n }}} = number of programs printed after the 
first {{{ 100 }}} 
-----------------
The equation is:
{{{ C = 10 + ( 6.6*n ) / 100 }}}
You are given:
{{{ C = 36.4 }}}
{{{ 36.4 = 10 + ( 6.6*n ) / 100 }}}
{{{ 35.4 = ( 6.6*n ) / 100 }}}
{{{ 3540 = 6.6n }}}
{{{ n = 3540 / 6.6 }}}
{{{ n = 536.36 }}}
-------------------
To this, you have to add the first {{{ 100 }}} programs
that cost {{{ 10 }}} pesos
{{{ n + 100 = 636.36 }}} 
Rounding this off, 636 programs were printed
( You don't print part of a program )
---------------------
Check answer:
{{{ C = 10 + ( 6.6*n ) / 100 }}}
{{{ C = 10 + ( 6.6*536.36 ) / 100 }}}
{{{ C = 10 + 3539.976 / 100 }}}
{{{ C = 10 + 35.399 }}}
{{{ C = 36.4 }}}
OK
