An electronic sign that showed the speed of motorists was installed on a road. The line
plots below show the speeds of some motorists before and after the sign was installed.
Based on these data, which statement is true about the speeds of motorists after the
sign was installed?
A The mean speed and the range of the speeds of the motorists decreased.
B The median speed and the range of the speeds of the motorists increased.
The mean speed of the motorists decreased and the range of the speeds increased.
D The median speed of the motorists increased and the range of the
speeds decreased.

answer:

125 yards

explanation:

75+50=125. that is my answer

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

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
