<span>Your Answer: D
Why....
You can make equations out of the information
Let L be Lin, G be Greg, and F be Fran
L = 4 + G ---"Lin sold 4 more shirts than Greg"
F = 3L ---"Fran sold 3 times as many shirts as Lin"
F + G + L = 51 ---"In total the three sold 51 shirts"
Use F + G + L = 51
Substitute the equations in for F and L (because you need to know the G) like this....
(3L) + G + (4+G) = 51
You still have a variable besides G in there... you can use the L= 4+G and substitute again so that there are only G's
( 3(4+G) ) + G + (4+G) = 51 ---- SIMPLIFY :D
( 12 + 3G ) + G + 4 + G = 51
12 + 3G + G + 4 + G = 51 ---Combine like terms
16 + 5G = 51 </span>
Answer:
Lydia's address is Cypress Street is: 51823
Step-by-step explanation:
Represent the digit as ABCDE such that:
A = Ones
B = Tens
C = Hundred
D = Thousand
E = Ten Thousand
Analyzing the statements one after the other:
The tens digit is 6 less than 7.
The thousands digit is twice the digit in the tens place.
The hundreds digit is the greatest even number that is less than 10.
The ones digit is the product of 5 and 1.
The ten thousands digit is the difference between the hundreds digit and the ones digit.

Answer:
What is the mean cost of all 12 trips?
$937.50 per trip
What was done wrong in the proposed solution?
In order for this solution to be correct, both employees should have taken the same number of trips since the weight per trip is equal for both of them. But in reality, the first employee took 2 more trips than the second employee, therefore, the weight of the first employee's trips should be higher. E.g. if both employees had taken 6 trips each, then the average cost per trip would have been $975.
Step-by-step explanation:
the mean cost of all 12 trips = [(7 x $750) + (5 x $1,200)] / (7 + 5) = ($5,250 + $6,000) / 12 = $11,250 / 12 = $937.50
