Ответ:
He estimated that he had about $9 worth of groceries
Step-by-step explanation:
Given that
Gallon of milk = $3.49
Three pounds of oranges = $1.14(3) = $3.42
Box of cereal = $3.46
Here the front end estimation should be applied that means only considered the number that shows in the front side and the remaining numbers should be zeros
Now applying the front end estimation, It shows like this
$3.49 => $3.00
$3.42 => $3.00
$3.46 => $3.00
Now sum of all 3 that comes 9
Therefore the second option is correct
