Pls me asap with 2 and (must show ! ) + lots of *brainliest*

B because his total anount of cost on 4 shirts and one pant must be less than $80.

4s < 80 - 24
4s < 56
s< 56/4
s < 14

So number 3 is A since his cost must be less than $14.

Number 2 is D 
Number 3 is B

2)This Is because answer choice D lines up with the equation
3) This is because 4*14 is the best answer choice given, C and D are 2 high, A is less than B, but B fits also, so B is the best answer.
(Hope it helps ^_^)
