Answer:
y=1.05x
Explanation:
The equation that represents the total cost, y, of x yogurts at the store is:
y = 1.05x
This is because the cost of one yogurt is $1.05, and the total cost of x yogurts is equal to the cost of one yogurt multiplied by the number of yogurts purchased, which can be expressed as:
y = $1.05x
Therefore, the equation that represents the total cost, y, of x yogurts at the store is y = 1.05x.
