Let the number of T-shirts ordered be represented by x.
The cost of x T-shirts is 7x dollars.
The total cost, including shipping, is 7x + 22 dollars.
We are given that the total cost of the order is $1,520.
Therefore, we can set up the equation:
7x + 22 = 1,520
Simplifying the equation, we have:
7x = 1,520 - 22,
7x = 1,498.
Dividing both sides of the equation by 7, we find:
x = 1,498 / 7,
x = 214.
Therefore, the principal ordered 214 T-shirts.
The correct answer is C. 214.
To find the unit rate, we need to determine the number of brake pads produced per hour.
In 3 hours, 48 brake pads were produced.
So, in 1 hour, the number of brake pads produced is 48 divided by 3, which is 16.
Therefore, the unit rate for brake pads produced per hour is 16 brake pads per hour.
The correct answer is D. 16 brake pads per hour.
