Answer 2

Callie multiplied incorrectly

Explanation:

Here we have 0.42 × 4.73 = 1.9866 then

1.9866 + 29.4 + 168 = 199.3866

we had 0.42 × 4.73 = 1.26 which is incorrect meaning that Callie multiplied incorrectly

Callie multiplied as follows

0.42 × 3 = 1.26 but what was in the question was

0.42 × 4.73 which is equal to 1.9866.
