Data:
5 → 80
y → 144
Solving: (They are proportional measures, the rule of three is made (directly proportional)
[tex] \frac{5}{y} = \frac{80}{144} [/tex]
multiply cross
[tex]80*y = 5*144[/tex]
[tex]80y = 720[/tex]
[tex]y = \frac{720}{80} [/tex]
[tex]\boxed{\boxed{y = 9\:cups}}\end{array}}\qquad\quad\checkmark[/tex]
