Let x be the amount of the Php80 chocolate in the mix (in kilograms).
Then the amount of the Php60 chocolate in the mix is the rest (24-x) kilograms.
The total cost of the mix then is 80x + 60*(24-x).
Per kilogram, the price of the mix is .
We want this price would be Php72.50 .
It gives you an equation
= 72.50.
To solve it, multiply both sides by 24 and then simplify step by step
80x + 60*(24-x) = 24*72.50
80x + 60*24 - 60x = 24*72.50
20x = 24*7250 - 24*60
x = = one click in Excel = 15.
Answer. 15 kilograms of the Php80 chocolate and 24-15 = 9 kilograms of the Php60 chocolate.
CHECK. = 72.50 Php. ! Precisely correct !
Solved.
