Keisha is babysitting at $8 per hour to earn money for a car. So far she has saved $1300. The car that Keisha wants to buy costs at least $5440. Write and solve an inequality to determine the amount Keisha still needs to earn for the car.

Answers

Answer:

$4100

Step-by-step explanation:

For Kaisha to get this car we have these information available

Amount saved = $1300

The cost of the car = $5400

Let The amount left to complete the car = k

We have this equation

K + $1300 = $5400

K = 5400 - 1300

K = 4100

Therefore Kaisha still needs to earn an additional amount of $4100 for the total amount of the car to be completed.

a profit of 24% was made wheb a book was sold for birr 34% find the selling price that would have given a profit 28%​

Answers

Answer:

$35.20

Step-by-step explanation:

Given that the profit of 24% was made on $34.10,

And Profit = Selling price - cost price,

Where profit is 24%, and selling price is $34.10, cost price = ?

Then, to find the cost price (z):

Assume the cost price be a 100% and the selling price of $34.10 be 124%

Hence, we have

$34.10 = 124%

z = 100%

Substitue

=> z / 34.10 = 100% / 124 %

=> 124z = 34.10 (100)

124z = 3410

Divide both sides by the coefficient of z which is 124

z = $27.50

Therefore, to find the selling price for a profit of 28%

We have 28% of 27.5 = 7.70

With equation of Profit = Selling price - cost price

We have 7.70 = Selling price - 27.50

Removing 7.7 from both sides

We have, Selling price = 27.50 + 7.70

=> Selling price = $35.20

Hence, the selling prices for a profit of 28% is $35.20
