Final answer:
To calculate the unit price of a 4-pack of sponges that costs $1.25, divide the total cost by 4 to get $0.3125 per sponge, then round to $0.31 per sponge.
Step-by-step explanation:
To calculate the unit price of a 4-pack of sponges that costs $1.25, you need to divide the total cost by the number of sponges in the pack. The unit price is found using the following steps:
1. Determine the total cost of the pack, which is given as $1.25.
2. Count the number of sponges in the pack, which is 4.
3. Divide the total cost by the number of sponges to find the unit price: $1.25 ÷ 4 sponges = $0.3125 per sponge.
4. Since we need to round to the nearest cent, the unit price becomes approximately $0.31 per sponge when rounded up.
The final rounded unit price is $0.31 per sponge, making it easier to compare the cost of these sponges with those sold in different quantities or at different prices.
