5. |
A T-shirt company charges a design fee of $25 and then sells the shirts for $10 each. The total cost y can be represented by the equation y = 10x + 25, where x represents the number of T-shirts. The graph of the equation is shown. Describe what the slope and y-intercept represent. |
| |
|
 |
| |
|
A. |
The slope represents the one-time design charge. The y-intercept represents the cost per T-shirt. |
| |
|
B. |
The slope represents the number of T-shirts. The y-intercept represents the cost per T-shirt. |
| |
|
C. |
The slope represents the total cost of the T-shirts. The y-intercept represents the one-time design charge. |
| |
|
D. |
The slope represents the cost per T-shirt. The y-intercept represents the one-time design charge. |
