a company charges $7 for a T-shirt and ships any order for $22 a school principal order number of t-shirts for the schools or the total cost of the order was $1,520 how many t-shirts to the principal order
Let's assume the number of T-shirts the principal ordered is "x".
The cost of x T-shirts would be 7*x = 7x dollars.
The shipping cost for the order would be 22 dollars.
So, the total cost of the order would be 7x + 22 dollars.
According to the given information, the total cost of the order was $1,520.
So, we can write the equation as:
7x + 22 = 1520
Subtracting 22 from both sides of the equation:
7x = 1520 - 22
7x = 1498
Dividing both sides of the equation by 7:
x = 1498 / 7
x ≈ 214
Therefore, the principal ordered approximately 214 T-shirts for the school.
