Answer:
$=19400
Step-by-step explanation:
Average prices= $18,500
Number of prices that were quoted= 7
Expected sum that produces this mean= 7*18,500=$129,500
Sum of quoted prices=
$(15,500+ 18,800+ 16,900+ 19,900+18,000+21,000) =$110100
Next price to be quoted will be ;
$129,500-$110,100
$=19400

Answer:
The answer is B.
Step-by-step explanation:
You just have to make equal fractions, so if c = 4 that means 
= 
so cross multiply to get 7a = 20; divide both sides by 7 to get a = 2.86 and do the same with the other ones
If c = 11 then = 
cross multiply to get 7a = 55; divide both sides by 7 to get a = 7.86 and so on
The answer is true to the other question
