Answer:
The regular size is more economical.
Step-by-step explanation:
Consider the provided information.
A regular tube of toothpaste costs $2.50 for 3.2 ounces.
Find out the unit rate as shown below:
Therefore, the cost of one ounce is $0.78.
A travel size tube costs $1.00 for 1.2 ounces.
Find out the unit rate as shown below:
Therefore, the cost of one ounce is $0.833.
From the above calculation we can observe that regular tube toothpaste price is better buy.
Now find the percent as shown:
Firs find the difference
$0.83-$0.78 = $0.05
Therefore,
Hence, regular tube is 6.41% less costly as compare to travel size.
Answer:
- y = 3 | x + 2 | - 5
Step-by-step explanation:
<u>The absolute value function is:</u>
- y = | x |
<u>Step 1. Function is vertically stretched by a factor of 3:</u>
- y = 3 * | x |
<u>Step 2. Shifted two units left:</u>
- y = 3 | x + 2 |
<u>Step 3. Shifted 5 units down:</u>
- y = 3 | x + 2 | - 5
