A grocery store sells a bag of 4 oranges for $1.72. If Christopher spent $1.29 on oranges, how many did he buy?

To solve this problem, we need to find out how much one orange costs and then determine how many oranges Christopher bought with $1.29.

Step 1: Determine the cost of one orange. The grocery store sells a bag of 4 oranges for $1.72. So, to find the cost of one orange, we divide the total cost of the bag by the number of oranges in the bag.$1.72 ÷ 4 = $0.43. So, one orange costs$0.43.

Step 2: Determine how many oranges Christopher bought. Christopher spent $1.29 on oranges. To find out how many oranges he bought, we divide the total amount he spent by the cost of one orange.$1.29 ÷ $0.43 ≈ 3.

So, Christopher bought approximately 3 oranges.
