Question

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?

Answer 1

Given data:

• A gallon of milk costs $3.49
• A pound of orange costs $1.14
• A box of cereal costs $3.46

To find:

• Estimation of the total cost

Solution:

• We need to find the total cost of all products.
• Cost of three pounds of oranges is
• = $(3 × 1.14)
• = $3.42

• Then the cost of all the products is
• = $(3.49 + 3.42 + 3.46)
• = $10.37

Answer:

• Thus total cost would be $10.37 which is $(10.37 - 10) = $0.37 higher than the amount given to him by his mother.

the cost is $10.47
