Shen's mother gave him $10 to go buy groceries. He picked up a gallon of milk for $3.49, three pounds of oranges that cost $1.14 per pound, and a box of cereal for $3.46. Shen used front-end estimation to determine whether he had enough money for the groceries. How much did he estimate the total cost would be? He estimated that he had about $7 worth of groceries. He estimated that he had about $9 worth of groceries. He estimated that he had about $10.30 worth of groceries. He estimated that he had about $10.40 worth of groceries.

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
