Ricardo has just taken over his parents' restaurant. He knows after working there for many years that one of the major concerns among employees is competitive pay. Specifically, Ricardo's servers think that they are paid less than servers in similar restaurants.
To help investigate this issue, Ricardo employs a company that specializes in gathering data about pay rates for similar positions across the state. The company provides Ricardo with the following box-and-whisker plot.
Ricardo's goal is to provide his servers with competitive pay compared to other restaurants in the state. He currently pays his servers hourly rates ranging from $8.50 to $11.50, depending on experience and seniority. His median server pay is $8.83. Based on what he sees in the plot above, which of the following is an appropriate conclusion for Ricardo?
A.
Ricardo's median is consistent with the state median. Ricardo should leave his servers' pay as it is.
B.
Most of Ricardo's servers are paid more than the state median. Ricardo should leave his servers' pay as it is.
C.
Ricardo's minimum, maximum, and median are all significantly less that those of the state. Ricardo should increase his servers' pay.
D.
Almost half of other servers across the state make more than the highest paid of Ricardo's servers. Ricardo should increase his servers' pay.

Ответ:
The cost per square foot of laminate flooring is $1.88 and the cost per square foot of carpet is $2.49
Step-by-step explanation:
Let
x -----> the cost per square foot of laminate flooring
y ----> the cost per square foot of carpet
we know that
750x+525y=2,717.25 -----> equation A
100x+75y=374.75 ------> equation B
Solve the system by graphing
The solution of the system is the intersection point both graphs
The solution is the point (1.88,2.49)
see the attached figure
therefore
The cost per square foot of laminate flooring is $1.88 and the cost per square foot of carpet is $2.49
