Answer:
$9.
Step-by-step explanation:
We have been given that 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.
In front-end estimation, we round whatever number is in front instead of rounding each number to a given place value.
We can see that in $3.49, front number is and second number is less than 5, so we will round it down to $3.
Similarly, in $3.46, 1st number is 3 and second number is less than 5, so we will round it down to $3.
In $1.14, front or 1st number is 1 and second number is less than 5, so we will round down to $1. Cost of three orange boxes would be .
Therefore, the total estimated cost of groceries is $9.
