Answer:
Part 1) Trinity 233/407
Part 2) Jason 174/407
Step-by-step explanation:
we know that
Trinity sold $2,330 and Jason sold $1,740
so
step 1
Find out the total sales
The total sales is equal to Trinity's sales plus Jason's sales
so
$2,330+$1,740=$4,070
step 2
The fraction of total sales that Trinity sold is equal to divide the sales of Trinity by the total sales
2,330/4,070
Simplify
233/407
step 3
The fraction of total sales that Jason sold is equal to divide the sales of Jason by the total sales
1,740/4,070
Simplify
174/407
Given that the concentration of salt in a 125 ml of salt solution is 20%, this means that the ratio of salt to water in the solution is 20 : 80 = 1 : 4.
Thus, the amount of salt in the 125 ml 20% salt solution is given by 20% of 125 = 0.2 x 125 = 25ml and the amount of water in the 125ml 20% salt solution is 125 - 25 = 100 ml.
When 25 ml of water is added to the 125 ml 20% salt solution, the new amount of water is 100 + 25 =125 and the amount of salt remain 25 ml.
Thus, the new volume of the solution is 125 + 25 = 150 ml and the proprtion of salt in the new solution is given by 25 / 150 = 0.1667
Therefore, the concentration of a new solution <span>obtained by mixing 25ml of water with 125ml of a 20% salt solution in water is 16.67%</span>
