The maximum number of shirts I can buy is 2.
14.50 x 2 = 29
14.50 x 3 = 43.5
Two shirts cost 29 dollars, and 3 shirts cost 43.5 dollars. Since $43.5 is higher than the money I currently have, I can only buy 2 shirts.
That would be 1^2 + 20 , 2^2 + 20 and 3^2 + 20 (replacing n by 1 , 2 and 3)
= 21, 24 and 29 Answer
The answer is 7x/12 - 1/2. Its the first option in your picture. Hope this helps .
