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 there were about $10.40 worth of groceries

10.45

So 10.45 is closest to 10.40 and you have to remeber that this is just an estimate so it will be less because we rounded the answer up.

Hope this helps

$9 its be heres my work

Step-by-step explanation:

Gallon of milk: $3.49

3lbs oranges: $1.14(3) = $3.42

Box of cereal: $3.46

Front end estimation is taking the number in front and the rest of the numbers coming after it will be zeroes.

Using front end estimation:

$3.49 => $3.00

$3.42 => $3.00

$3.46 => $3.00

Add all these up; Shen estimated the total cost of the groceries would be $9.00.
