Answer:

Flynn got the right answer.

[tex]825\times 22 = 18150[/tex]

Step-by-step explanation:

We are given two persons Jane and Flynn. They carried out multiplication of two same numbers but got different product.

We need to check who performed the correct calculation.

[tex]825\times 22[/tex]

Jane received an answer of 3,300 and Flynn got an answer of 18,150.

The right product is:

[tex]825\times 22\\=825\times(20+2)\\=16500 + 1650\\=18150[/tex]

Thus, Flynn got the right answer.

Jane got the wrong answer. Maybe she copied down the wrong numbers. Jane multiplied 825 by 4 instead of 22.[tex]825\times 4 = 3300[/tex]
