A student was at Hobby Middle school to determine which
movie 7th graders preferred: The results are shown below:
-Hunger Games was preferred by 15 students-Divergent was
preferred by 10 students
Based on the results of the survey, how many of the 300, 7th
graders would prefer Divergent?
a) 75
b) 12
c) 7.5
d) 120

120

Step-by-step explanation:

Hunger Games=15

Divergent=10

15+10=25 (total number of votes)

10/25=0.4 or 40% of the students

0.4*300=120

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
