Answer:
- Unit price of a 2-liter bottle of soda:

- Unit price of a case of twelve 12 ounce cans:

- The better bargain is the case of 12 ounce cans.
Step-by-step explanation:
Let be "x" the unit price (price/ounce) of the soda in the 2-liter bottle and "y" the unit price (price/ounce) of the soda in the case of twelve 12 ounces cans.
According to the data provided in the exercise, you know that:
1. The 2-liter bottle of soda is equal to 67.6 ounces.
2. That bottle costs $1.89
Then, the unit price is:

3. There are 12 ounce cans in the case. Then the total ounces is:

4. It costs $2.99. So the unit price is:

Since:

The better bargain is the case of 12 ounce cans.
Answer:
t = 1 1/4 hours
Step-by-step explanation:
Lets first make an equation to represent the situation. t + 1/2 = 1 3/4
Because we cant add fractions with different denominators we have to change 1/2 to 2/4.
Next, we need to isolate t. Subtract 2/4 from both sides of the equation to get 1 1/4.
t = 1 1/4.
Answer:
14x²(2x³ + 1)
Step-by-step explanation:
Split the value: 28x⁵
28x⁵ = 28x³x²
14x² + 28x³x²
28 = 14 × 2
14x² + 14 · 2x³x²
Factor:
14x²(2x³ + 1)
