Data:
Tape size = 1224 cm → 12.24 m
Price per size = $0.75/m

Solving: Rule of three (directly proportional)

$ (price) __ (Size)
0.75 ----------- 1 m
y --------------- 12.24 m

Multiply cross


y = 0.75*12.24

\boxed{\boxed{y = \$\:9.18}}\end{array}}\qquad\quad\checkmark

Answer:
She paid for the tape $ 9.18
