A teacher Buys tickets for each of my students to visit a museum each student and $6.50 and she spent a total of $182 how many s

vaieri [72.5K]

Answer:

The ticket is bought for 28 students.

Step-by-step explanation:

It is given that the teacher is going to buy museum ticket for each students.

Total money spent = $182

Price of each ticket = $6.50

Let total number of tickets bought = $x$

We know that to find the total amount of money spent on ticket, we can add price of each ticket (i.e. $6.50) $x$ number of times.

In other words, simply multiply the number of tickets with price of each ticket to find the total money spent.

Total money spent = $x \times 6.50$

We know that total money spent is $182.

$\Rightarrow x \times 6.50 = 182\\\Rightarrow x = \dfrac{182}{6.50}\\\Rightarrow x = 28$

Two numbers are in the ratio 7:5 and their difference is 22.Find the numbers

omeli [17]

Answer:

Let x and y be the two numbers. Then

yx=57 and x−y=20

Cross multiplying the proportion

5x=7y or y=75x

So, x−y=20

x−75x=20⇒77x−5x=72x=20

⇒x=2140=70

y=75x=75×70=50

So smaller number is 50.

Check :yx=5070=57 and 70−50=20
