Note: Make the rule of three simple
cartoons __ price $
3 --------------- 4.77
8 --------------- y
Solving: (directly proportional)
[tex] \frac{3}{8} = \frac{4.77}{y} [/tex]
Product of extremes equals product of means
[tex]3*y = 8*4.77[/tex]
[tex]3y = 38.16[/tex]
[tex]y = \frac{38.16}{3} [/tex]
[tex]\boxed{\boxed{y = 12.72}}\end{array}}\qquad\quad\checkmark[/tex]
