Final answer:
The equation for the total charges y in dollars for ordering x shirts is y = 10x + 110.
Step-by-step explanation:
To write an equation for the total charges y in dollars for ordering x shirts, we need to consider the cost of the shirts and the cost of shipping.
The cost of each shirt is $10, so the cost of x shirts is 10x dollars. And the shipping charge is $110. To find the total charges, we add the cost of the shirts and the shipping charge, giving us the equation:
y = 10x + 110
