Answer:
The cost in dollars and the amount of yogurt are proportional
Step-by-step explanation:
Proportions
Two variables are proportional if the ratio or division between them is a constant value.
Kareem buys a 32-oz container of yogurt for $2.56. We can compute the ratio of the quantity of yogurt and price 32/2.56 and we get 12.5. Jonah buys a 6-oz container of yogurt for $0.48. The relation is now 6/0.48=12.5
Since both ratios are equal, we can say the amount of yogurt, and the cost in dollars are proportional variables

The total cost of the breakfast is $19.26 if the cost of the breakfast is $18 and the tax added is 7%.
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
The cost for the breakfast = $18
The tax added = 7%
Let T be the total price of the breakfast after-tax added:
T = $18 + 7% of $18
T = 18 + (7/100)18
T = 18 + 0.07x18
T = 18 + 1.26
T = $19.26
Thus, the total cost of the breakfast is $19.26 if the cost of the breakfast is $18 and the tax added is 7%.
The question is incomplete; the complete question is:
How much is an $18.00 breakfast if a 7% tax was added?

Step-by-step explanation:
Third month Gina's payrate will be $9.9 per hour.
Given that,
According to the given data, calculation of the given data are as follows,
Second month earning = $10 + ( $10 10%)
= $10 + $1
= $11 per hour
Third month's earning = $11 - ( $11 10%)
= $11 - $1.1
= $9.9 per hour
So, third month pay rate will be $9.9.
