Given that ribbon cost $0.21 per centimeter, if Kaia bought 50 millimeters of ribbon for wrapping gifts, she will pay $9.45.

How much did Kaia pay for the ribbon?

Given that;

  • 1 ribbon cost $0.21 per centimeter
  • She bought 450 millimeters of ribbon

First we convert 450 millimeters to centimeters

1 centimeter = 10millimeters

Hence,

She bought 450 millimeters of ribbon = 45 centimeters of ribbon

Now,

1 cm of ribbon =  $0.21

45 cm = y

We cross multiply

y = 45 × $0.21

y = $9.45

Therefore, given that ribbon cost $0.21 per centimeter, if Kaia bought 50 millimeters of ribbon for wrapping gifts, she will pay $9.45.
