p = -10 and p = -5
Step-by-step explanation:
Given inequality,
![90 < -30 p + 15](/tpl/images/0472/7990/62643.png)
Subtract -15 on both sides of inequality,
![90 - 15 < -30 p](/tpl/images/0472/7990/4acd2.png)
![75 < -30 p](/tpl/images/0472/7990/40e09.png)
Divide both sides of inequality by 30
![2.5](/tpl/images/0472/7990/ac874.png)
Β ( a < b β -a > -b )
![-2.5p](/tpl/images/0472/7990/bce3e.png)
Hence, p must be less than -2.5
So, the possible value of p from the given options are,
p = -10 and p = -5.
