A stock of food is enough to feed 50persons for 14 days.How many days will the foos last if 20 more person will be added?

Sagot :

This is a proportion.
[tex] \frac{50}{14} = \frac{70}{x} [/tex]
Next step is to cross multiply.
[tex]50x = 980[/tex]
Next we divide both sides by 50.
[tex]x = 19.6[/tex]

Answer is 19.6, if rounded off it's 20 days.
