Kaitlan sold 60% of her hockey card collection at the fall market sale. If she sold 240 cards, how many cards were in her collection?

Answers

Answer 1

Answer:

400

Step-by-step explanation:

Ok so if 60% of the total is 240 than create an expression:

60% of x=240

Now divide both sides by 3:

20% of x=80

Multiply both sides by 5 ( because 5 times 30 is 100):

100% of x=400

Thats the answer hope this helped! :)

Answer 2

400 cards were in her collection.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Total hockey cards sold= 240

So, Kaitlan sold 60% of her hockey card

let the total number of Hockey cards be x.

So, 60% of x= 240

60 x /100 = 240

x= 24000/ 60

x= 400

Hence, 400 cards were in her collection.

What single percentage change is equivalent to a 15% decrease followed by a 16% decrease?

Answers

Decrease of 28.6%.

Step-by-step explanation:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

Decrease of 15%

1- 15/100 = 1- 0.15 = 0.85

Decrease of 16%

1- 16/100 = 1 - 0.16 = 0.84

Both:

0.85*0.84 = 0.714

Change:

The initial percentage is 100% = 1.

0.714 - 1 = -0.286

Negative, so a decrease

The answer is a decrease of 28.6%.

Identify the y-intercept of y=4x - 2/3

Answers

The y-intercept of the equation y = 4x - 2/3 is 2/3.

Answer:

y- intercept = - [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 4x - [tex]\frac{2}{3}[/tex] ← is in slope- intercept form

with y- intercept c = - [tex]\frac{2}{3}[/tex]

Katia makes crafty using glass jars she can buy a package of 12 jars for nine dollars

Answers

Answer:

swer:

Katia bought 60 jars with $45.

Solution:

From Question,  

Katia bought a package of 12 jars = $ 9.

So, we need to find that how many jars katia can buy with $45.  

12 jars bought for 9 so per 1 jar price can be calculated by dividing 12 by 9

= 1.33

So, 1 jar price is $1.33

From the Question, So for $45 the jar bought is calculated by multiplying price of one jar and 45

1.33  45 = 60.

Hence we can conclude 60 jars bought for $45 by katia for making crafts using glass jars.
