Answer:
Step-by-step explanation:
The equations that she wrote are
6x+8y=133
2x=y
The following statements about the system are true
1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133
5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.
The following statements are wrong because,
2. Because there was no relationship between the number of pipes sold and the size of each pipe.
3. x=2y shows that there are more 8 inches pipes
4. 6 and 8 are just size descriptions. It is only the cost of each size of pipe that related to the total cost
Answer:
Cost per ounce = $0.07 (7 cents per ounce)
Step-by-step explanation:
Each container is 7.8 ounces and there are 24 of them in a case.
<u>Total weight</u> in ounce of the case is:
7.8 * 24 = 187.2 ounces
It costs $12.99 for the case, which contains 187.2 ounces. We find the cost per ounce of yogurt by dividing the total cost by total ounces in the case.
12.99/187.2 = 0.0693
Rounded to nearest cent (2 decimal places), that would be:
Cost per ounce = $0.07 (7 cents per ounce)
