Ashop is having a sale on t-shirts. if you buy the first t-shirt for $17, each additional t-shirt will cost $5. which formula models this situation?

an=17+(n-1)x5

an=5+(n-1)x17

an=22=(n-1)x5

an=(n-1)x17

Step-by-step explanation:

I would have just written it like : 17 + 5n...but thats not there...so if n = total t -shirts bought, then ur equation is : An = 17 + (n - 1) * 5

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
