Final answer:
To find the number of T-shirts ordered, use the equation 1,520 = 7x + 15.
Step-by-step explanation:
To find the number of T-shirts ordered, we can create an equation based on the given information. Let x represent the number of T-shirts ordered.
The cost of the T-shirts can be calculated by multiplying the price ($7) by the number of shirts (x). The cost of shipping is a fixed amount of $15.
Therefore, the equation that represents the total cost of the order is:
1,520 = 7x + 15
Simplifying the equation, we can find the value of x.
