Final answer:
To find the unit price of the detergent, we divide the total cost by the quantity, $6.99 by 90 fl. oz, which gives us approximately 7.77 cents per fl. oz, rounding up to 8 cents.
Step-by-step explanation:
The subject of the question involves calculating the unit price of detergent. To calculate the unit price, divide the total cost by the quantity. Here, we have 90 fl. oz of detergent for $6.99.
The unit price is calculated as follows:
- Divide the total cost ($6.99) by the total volume (90 fl. oz).
- $6.99 ÷ 90 fl. oz = approximately $0.0777 per ounce.
- To find the price per fluid ounce in cents, we multiply by 100: $0.0777 × 100 = 7.77 cents per fl. oz.
Therefore, the unit price for the detergent is approximately 7.77 cents per fluid ounce, which rounds to 8 cents when rounded to the nearest cent.
