David sold a bicycle at a profit of 10% had he sold it for rupees 150 more, the profit would have been 15%. find the cost price

dlinn [17]

Answer:

The cost price was 3,000 rupees.

Step-by-step explanation:

A profit is an excess of the cost price you bought the bicycle at.

The original cost price as a decimal = 1.0

10% profit in excess of original cost as a decimal = 1+ 0.10 = 1.10

15% profit in excess of original cost as a decimal = 1+0.15= 1.15

And if he sold the bicycle at 150rupees more, he makes 15% profit;

The differential percentage = 15%-10% = 5% or 0.05

If 5% = 150 rupees

then 100% = (100*150)/5

= 15,000/5

= 3,000 rupees

<u>To verify;</u>

<em>At 15% profit it would be = 3000*1.15 =3,450 rupees</em>

<em>At 10% profit , it would be = 3000* 1.10 = 3,300 rupees</em>

<em>Difference = 3,450 -3,300 = 150 rupees</em>

Therefore, the cost price was 3,000 rupees.

What can you say about the y-values of the two functions <img src="https://tex.z-dn.net/?f=f%28x%29%20%3D%203%5Ex-3" id="TexForm

slavikrds [6]

Answer:

a) The minimum y-value of f(x) is -3

d) The minimum y-value of g(x) is -3

Step-by-step explanation:

Given in the question that,

f(x) = 3 $^{x}$ -3

g(x) = 7x² - 3

At large negative exponents, the value approaches to zero

y = $3^{-100}-3=-3$

y = $3^{-1000}-3=-3$

y = $3^{-10000}-3=-3$

Minimum y-value of g(x) will be when x = 0

y = 7x² - 3

y = 7(0) - 3

y = -3

You are paid $82.50 for 7 1/2 hours of work, whats is your rate of pay?

ra1l [238]

Answer:

Rate of Pay is $11 per hour.

Step-by-step explanation:

Cost of $7\frac{1}{2}\:hr$ of work = $ 82.50

To find: Rate of pay

Here Rate of Pay means Cost of 1 hour of work or we can say cost of per hour work.

$7\frac{1}{2}=\frac{7\times2+1}{2}=\frac{15}{2}$

⇒ Cost of $\frac{15}{2}\;hr$ of work = $ 82.50

Cost of 1 hr of work = $\frac{82.50}{\frac{15}{2}}$

= $\frac{82.50\times2}{15}$

= $\frac{165}{15}$

= $ 11

Therefore, Rate of Pay is $11 per hour.
