Arianna is deciding between two different movie streaming sites to subscribe to.

Arianna is deciding between two different movie streaming sites to subscribe to.

Plan A costs $32 per month plus $1 per movie watched. Plan B costs $7 per month plus $2 per movie watched. Let A represent the monthly cost of Plan A if Arianna watches x per month, and let B represent the monthly cost of Plan B if Arianna watches x movies per month. Write an equation for each situation, in terms of x, and determine the number of monthly movies watched, x, that would make the two plans have an equal monthly cost.

 

Solution:

For the first plan:  cost 32$ + $1 per movie == 1.x + $32

For the second plan: cost $7 + $2 pe movie == 2.x + $7

For the two plans have an equal monthly cost.:

x + 32 = 2x + 7

x = 25.

So,  if Arianna watch 25 movie monthly, cost is equal for the two plans.

An apprentice baker made 40 liters of 60% sugar syrup instead of 40 liters of 45% sugar syrup.

An apprentice baker made 40 liters of 60% sugar syrup instead of 40 liters of 45% sugar syrup.

How much syrup should she drain and replace with distilled water so that the resulting solution is 40 liters of 45% syrup?

 

Solution:

Firstly, lets find the only syrup. 40 liters of 60% sugar syrup == 26 liters syrup and 16 litres water.

For the 45% syrup, we must add some woter. We have 26 liters syrup.

If we have a 45% sugar syrup, we need 31.7 liters water for 26 liters syrup.

At the begining, we had 16 liters water. So 31.7 – 16 = 15.6 liters added water.

A car is traveling at 60 mph. If the rate of speed increases 4 mph each hour

A car or train is traveling at 60 mph. If the rate of speed increases 4 mph each hour, how long will it be before the car is traveling at a rate of 80 mph?

It is an easy math question. Lets look the answer together.

A) 4 hours
B) 5 hours
C) 6 hours
D 7 hours​

Solution:

The speed increases 4 mph every hour from 60 to 80.

80 mph – 60 mph = 20 mph.

There are 12 men on an island. 11 weigh exactly the same amount, but one of them is slightly lighter or heavier.

Riddle: There are 12 men on an island. 11 weigh exactly the same amount, but one of them is slightly lighter or heavier. You must figure out which. The island has no escapes, but there is a seesaw. The exciting catch? You can only use it three times.

It is both a real puzzle and a real question of intelligence. It is a good question that you can have fun with your family or friends. Let’s tell the solution step by step.

First, let’s divide 12 people into groups of 4.

As a second step, Let’s put 2 groups of 4 people on seesaw. If it is the same, the slightly lighter is in the 3rd group. If it doesn’t come in equal weight, let’s separate the lighter group. In this way, we find the group of 4 with the slightly lighter or heavier person. We used the seesaw firts time.

Let’s divide 4 people into 2 groups. Then, Let’s take 2 people on the seesaw and find the light or heavy one. In this way, we will find the person we are looking for in a maximum of 2 attempts.
