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