Answer:

The solution for the inequality is -8 < x < -4

Step-by-step explanation:

Consider the provided inequality.  

-68 < 8x -4 < -36

-64 < 8x < -32

Divide the inequality by 8.

-8 < x < -4

Hence the solution for the inequality is -8 < x < -4

Answer:

The answer to question is:   -17/2 < x < -4

Step-by-step explanation:

Add +4                                  - 68 + 4 < 8x - 4 + 4 < - 36 +4

Simplify                                  -68 < 8x < - 32

Divide by 8                             -68 / 8 < 8/8 x < -32/8

Simplify                                  -17/2 < x < -4

Halim makes a profit of 120% on his cost price by selling a pair of shoes of $45. i) Find the cost pricer of the pair of shoes i
Rus_ich [418]

Answer:

a. $20.45

b. $24.55

c. $4.55

Step-by-step explanation:

In this question, we are asked to calculate the cost price and profit or loss selling a pair of shoes.

we proceed as follows

Firstly, we want to find the cost price given the selling price and the mark up percentage.

mathematically;

profit =( selling price - cost price)/cost price * 100%

here our profit is 120% with the cost price being $45. we plug these values

120 = 45-cp/cp * 100%

120cp = 100(45-cp)

120cp = 4500 -100cp

220cp = 4500

cp = 4500/220 = $20.45

His profit is selling price - cost price = 45 - 20.45 = $24.55

His profit selling same shoe for $25 is 25-20.45 = $4.55
