Answer:
$38.5
Explanation:
First we need to convert 250 centimeters to meters:
250 cm = 2.5 m
To find how much did Mimi pay for the fabric, we can use a rule of three:
One meter of fabric costs $15.40, so what is the cost of 2.5 m?
1 m -> 15.4
2.5 m -> x
x = 15.4 * 2.5 = $38.5
Mimi will pay $38.5 for the 250 centimeters of fabric.
