16. Carlos sells video games on Web site. The cost for his web site is $75 per year. Carlos sells each video game for $25. What inequality can Carlos use to determine g, the number of video games he must sell to make a profit of at least $50 per year?
A.100g less than and equal to 50
B.100g+75 less than or equal to 50
C.75g+25 greater than or equal to 50
D.25g+75 less than or equal to 50
E.25g-75 greater than or equal to 50
Choice c is wrong. I think its choice E.
profit, p = revenue, r - cost, c
r = revenue = 25 g
c = cost = 75
so
p = 25 g - 75
so if p >/= 50
then
25 g - 75 >/= 50
so you are right. It is E.
