Aman has a solution that is 35% iodine and 65% water, and another that is 15% iodine. how many gallons of the 15% solution should he combine with the first solution to get 2500 gallons of a 20% iodine solution?

There is 1875 gallons of the 15% solution should be combined with the first solution to get 2500 gallons of a 20% of iodine solution.

Step-by-step explanation:

Since we have given that

In first solution , Percent of iodine solution = 35%

In second solution, Percent of iodine solution = 15%

Let the number of gallon of 15% solution be x

Let the number of gallon of 35% solution be 2500-x

According to question,

Hence, there is 1875 gallons of the 15% solution should be combined with the first solution to get 2500 gallons of a 20% of iodine solution.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
