3. At a bargain store, Spongebob bought 3 items that each cost the same amount. Patrick bought 5 items that each cost the same amount, but each was $1.50 less than the items that Spongebob bought. Both Spongebob and Patrick paid the same amount of money. What was the individual cost of each person's items?

Answers

Answer: Cost of each item bought by Spongebob = $2.5

Cost of each item bought by Patrick = $1

Step-by-step explanation:

Let x be the cost of each item bought by Spongebob.

Then, cost of each item bought by Patrick = x- 1.50

Then, cost of 3 items bought by Spongebob = 3x

Cost of 5 items bought by Patrick = 5(x-1.50)

If both Spongebob and Patrick paid the same amount of money then

$3x= 5(x-1.5)\n\n\Rightarrow\ 3x=5x-1.5*5\n\n\Rightarrow\ 3x=5x-7.5\n\n\Rightarrow\ 5x-2x=7.5\n\n\Rightarrow\ 3x=7.5\n\n\Rightarrow\ x=(7.5)/(3)\n\n\Rightarrow\ x=2.5$

Cost of each item bought by Spongebob = $2.5

Cost of each item bought by Patrick = $2.5-$1.5=$1

Hence, Cost of each item bought by Spongebob = $2.5

Cost of each item bought by Patrick = $1

Answer: Cost of each item bought by Spongebob = $2.5

Cost of each item bought by Patrick = $1

Step-by-step explanation:

Let x be the cost of each item bought by Spongebob.

Then, cost of each item bought by Patrick = x- 1.50

Then, cost of 3 items bought by Spongebob = 3x

Cost of 5 items bought by Patrick = 5(x-1.50)

If both Spongebob and Patrick paid the same amount of money then

Cost of each item bought by Spongebob = $2.5

Cost of each item bought by Patrick = $2.5-$1.5=$1

Hence, Cost of each item bought by Spongebob = $2.5

Cost of each item bought by Patrick = $1

Ms. Chang has 24 students in her class, and 6 of them are boys. What is the ratio of boys to girls?

Answers

The total number of students is 24 and the total number of boys is 6, therefore

Number of girls = 24 – 6 = 18

Therefore the ratio of the boys to girls is

Number of boys/ number of girls = 6/18 ~ 1/3

The ratio suggests that there is 1 boy for every 3 girls

Next-door neighbors Bob and Jim use hoses from both houses to fill Bob's swimming pool. They know that it takes 12 h using both hoses. They also know that Bob's hose, used alone, takes 20% less time than Jim's hose alone. How much time is required to fill the pool by each hose alone?

Answers

Final answer:

Jim's hose takes 15 hours while Bob's hose takes 12 hours to fill the pool when used individually.

Explanation:

This is a mathematical problem that can be solved using the concept of rates.

Let x be the time taken by Jim's hose to fill the pool alone. Since Bob's hose is 20% faster, it takes 0.8x hours to fill the pool alone. We know that work done is inversely proportional to the time taken, we set up the equation 1/x + 1/0.8x = 1/12 (since together they fill the pool in 12 hours).

On solving this equation, we get x= 15 hours (Jim's hose) and 0.8x = 12 hours (Bob's hose).
