The scatterplot shows the average number of hours each of 13 people spends at work every week and the average number of hours each of them spends on recreational
activities every week.

Based on the scatterplot, what is the best prediction of the average number of hours a
person spends at work every week if that person spends an average of 10 hours on
recreational activities every week?

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200

you are having disney spells!

the answer is  

d.

hope you got it down chief.
