A market stall holder bought a variety of coloured 'hoodies' to sell. Each hoodie costs the stall holder $20 and she intends to sell them to the public at a mark up of 65%

1) What profit does the stall holder make on the sale of each hoodie?

Answers

Original price = $20

Markup percentage = 65

Markup amount = 0

What is the profit?

65% of 20 = $12

Therefore Markup amount = $12

Profit = Original price + markup amount
= $20 + $12
= $32

Answers

Answer:

Yes

Step-by-step explanation:

So we know that 3/4 is equivalent to 9/12, because 3×12=36 and 4×9=36. A simple way to look at how to check for equivalent fractions is to do what is called “cross-multiply”, which means multiple the numerator of one fraction by the denominator of the other fraction.

Answer:

7/5

Step-by-step explanation:

Find the first point that the line intersects which is (-4,-3)

Then find the second point the line intersects which is (1, 3)

Since you have a graft you can just count the how many up and to the right the points are from each other (rise/run)

Do they tell you what the numbers are? Like what are the coordinate points going by? That would help. Once you know, just do y1-y2/x1-x2. (first y coordinate minus second y value divided by second x coordinate minus the first. This'll give you a number, and that number is your m in y-mx plus b.)

write an explicit formula for a n the nth term of of the sequence 5,15,25

Answers

Answer:

an = 10n - 5

Step-by-step explanation:

Write an explicit formula for a n the nth term of of the sequence 5,15,25

An explicit formula for the above question is;

an = a+ (n - 1)d

Where

a = First term

d = Common Difference

n = nth term

We are given the sequence below:

5,15,25

The first term a = 5

Common Difference = 15 - 5 = 10

To find the nth term = an

an = a+ (n - 1)d

an = 5 + (n - 1)10

an = 5 + 10n - 10

an = 10n - 5

If you buy 3 shirts, you get 10% discount. If you paid $270 for 6 shirts
what is the original price of a T-shirt?

Answers

First we are gonna divide 270 by 2


$270 / 2 = $135

This is the price of 3 T shirts combined.

Find 10% of 135

10% of $135 is $13.5

Subtract the discounted price from the price of the 3 combined T shirt.

$135 - $13.5 = $121.5

This is the price of 3 shirts without discount.

To find the price of 1 T shirt divide $121.5 by 3

$121.5 / 3 = $40.5

Therefore the price of 1 T shirt is $40.50

The original price of 1 T-shirt is $40.50.

We have given that,

If you buy 3 shirts, you get 10% discount.

If you paid $270 for 6 shirts,

We have to determine the original price of a T-shirt

First we are gonna divide 270 by 2

$270 / 2 = $135

This is the price of 3 T-shirts combined.

Find 10% of 135

What s the discount?

The discount is the list price minus the sale price then divided by the list price and multiplied by 100 to get a percentage.

10% of $135 is $13.5

Subtract the discounted price from the price of the 3 combined T-shirt.

$135 - $13.5 = $121.5

This is the price of 3 shirts without a discount.

To find the price of 1 T-shirt divide $121.5 by 3

$121.5 / 3 = $40.5

Therefore the price of 1 T-shirt is $40.50.

Answers

The answer is the first one: (z+1)(y+6).

Explanation:

yz + 6 + y + 6z

= yz + y + 6 + 6z

= y(z+1) + 6(1+z)

= (z+1)(y+6)

For (z+1), you can also write (1+z), it doesn’t matter.
