one bottle of shampoo costs $6 for 8 ounces.A second bottle costs $4 for 5 ounces of shampoo.Which has the lower unit rate?How much lower?
6/8 = $0.75 per ounce
4/5 = $0.80 per ounce
The one who the lower unit rate is 6/8
To determine which bottle of shampoo has the lower unit rate, we need to calculate the cost per ounce for each bottle.
For the first bottle of shampoo that costs $6 for 8 ounces, we can divide the cost by the number of ounces: $6 / 8 = $0.75 per ounce.
For the second bottle of shampoo that costs $4 for 5 ounces, we can divide the cost by the number of ounces: $4 / 5 = $0.80 per ounce.
Comparing the two unit rates, we find that the first bottle has a lower unit rate of $0.75 per ounce.
To calculate how much lower the unit rate is for the first bottle, we subtract the unit rates. The unit rate of the first bottle ($0.75 per ounce) minus the unit rate of the second bottle ($0.80 per ounce) equals $0.05 per ounce lower.
Therefore, the first bottle of shampoo has a lower unit rate by $0.05 per ounce compared to the second bottle.
