Winston would need to sell 14 more hot dogs to earn $175

Step-by-step explanation:

The given is:

Winston earns $140 by selling 56 hot dogs
He is using the same rate for the cost of one hot dog
He want to earn $175

We need to find how many more hot dogs would Winston need to sell to earn $175

∵ The he sold 56 hot dogs for $140

- Find the price of each hot dog by dividing 140 by 56

∴ The price of each hot dog = 140 ÷ 56 = 2.5

∴ The price of each hot dog is $2.5

∵ He need to earn $175

∵ He sells all hot dogs by the same price

- Divide 175 by 2.5 to find the number of the hot dogs

∵ 175 ÷ 2.5 = 70

∴ He must sell 70 hot dogs to earn $175

∵ He already sold 56

- Subtract 56 from 70 to find how many more hot dogs he

needs to sell

∵ 70 - 56 = 14

∴ He must sell another 14 hot dogs to earn that money

Winston would need to sell 14 more hot dogs to earn $175

Basile [38]

Answer:

a) 0.8841

b) 0.0435

Step-by-step explanation:

A : the set of joints deemed defective by inspector A.

B: the set of joints deemed defective by inspector B.

U: the set of all joints.

The problem says |A|=724, |B|=751, |A∪B|=1159, |U|=10000. Hence, with the help of Venn diagram we can answer the following:

Part a)

This asks for the number of joints that are ∉(A∪B).

hence,

P (∉(A∪B)) :

$\frac{10000-1159}{10000} \\\\=0.8841$

part b)

This asks for the number of joints that are in B but not in A, which Is represented as the set B−A

$= \frac{|B| - |AandB| }{|U|}\\\\= \frac{751-316 }{10000}\\\\= 0.0435$

If nthe shop has a mark up rate of 50% and they cost 300 to buy you multiply 300 by 50% convert 50% to decimal
so you do .5*300=150
then you add 150 to 300 which means that the shop sells the skis for 450 dollars.

Please help me I have been stuck on this question for ages

Finger [1]

Answer:28 green and 35 red

Step-by-step explanation:

Given

If there are r red counter and g green counter then

Probability of drawing a green counter is $P(g)=\frac{4}{9}$

and $P(g)=\frac{\text{No of g counter}}{\text{Total no of counter}}$

Thus $\frac{\text{No of g counter}}{\text{Total no of counter}}=\frac{4}{9}$

$\frac{g}{g+r}=\frac{4}{9}$

$\Rightarrow 9g=4g+4r$

$\Rightarrow 5g=4r\quad \ldots(i)$

Also if 4 red and 2 green counter is added the probability of drawing a green counter is

$P(g)=\frac{10}{23}=\frac{\text{No of g counter}}{\text{Total no of counter}}$

$\Rightarrow \frac{10}{23}=\frac{g+2}{g+2+r+4}$

$\Rightarrow \frac{10}{23}=\frac{g+2}{g+r+6}$

$\Rightarrow 10g+10r+60=23g+46$

$\Rightarrow 10r+14=13g\ quad \ldots(ii)$

Substitute the value of g in equation (ii)[/tex]

$\Rightarrow 10\times \frac{5}{4}g+14=13g$

$\Rightarrow \frac{25}{2}g+14=13g$

$\Rightarrow g=28$

Therefore $r=35$

Thus there 28 green counter and 35 red counter

Jill gets a base pay of $1500 per month. She also earns a commission of 8% of her total sales. What are Jill's earnings for a mo

mart [117]

Answer:

$4060.

Step-by-step explanation:

We have been given that Jill gets a base pay of $1500 per month. She also earns a commission of 8% of her total sales. We are asked to find Jill's earnings for a month in which she has sales of $32,000.

Jill's earnings for the month would be base salary pus 8% of $32,000.

$\text{Jill's total earnings for the month}=\$1500+\$32,000\times \frac{8}{100}$

$\text{Jill's total earnings for the month}=\$1500+\$320\times8$

$\text{Jill's total earnings for the month}=\$1500+\$2560$

$\text{Jill's total earnings for the month}=\$4060$

Therefore, the Jill's earnings for the given month would be $4060.
