If p∨q is true, then what must be true about the truth values of p and q?

where p and q are statements, "p and q" is false if
p is false.
which of the following statements is the contrapositive of "if i have money, then i spend it"?

if i don't have money, then i don't spend it.
if i spend money, then i have it.
if i don't spend money, then i don't have it.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
