A company charges $7. For a T - shirt and ships any order for $22. A school principal ordered a number of T - shirts for the school store. The total cost of the order was $1, 520. How many T - shirts did the principal order?
Let x be the number of T-shirts ordered.
The cost of the T-shirts is 7*x.
The total cost of the order is 7*x + 22 = $1,520.
7*x + 22 = $1,520
7*x = $1,520 - $22
7*x = $1,498
x = $1,498 / 7
x = 214
The principal ordered 214 T-shirts. Answer: \boxed{214}.
