Servers at a snack shop use the table below to find the total cost for frozen yogurt, but some of the numbers have worn off. The total cost is proportional to the number of cups of frozen yogurt. Find the missing numbers in the table.
Answer :
Final answer:
To find the missing numbers in the table, we can set up a proportion and solve for the missing value. In this case, the total cost is proportional to the number of cups of frozen yogurt. The missing number in the table is 90.
Explanation:
To find the missing numbers in the table, we need to understand that the total cost is proportional to the number of cups of frozen yogurt. In other words, the cost per cup of frozen yogurt is constant.
Let's look at the given numbers in the table:
Cups of Frozen Yogurt (x) - Total Cost (y)
3 - 15
6 - ?
9 - 45
Since the total cost is proportional to the number of cups, we can create a proportion and solve for the missing number:
3/15 = 6/y = 9/45
Cross-multiplying, we get:
3y = 6 * 45
3y = 270
y = 90
Therefore, the missing number in the table is 90. The complete table is:
Cups of Frozen Yogurt (x) - Total Cost (y)
3 - 15
6 - 90
9 - 45
