David wants to buy a large screen television that cost 1800$. If he buys it today ,he can save 30%.How much will the television cost if he buys it today?

step-by-stp

the correct answer is the section c

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
