A: the discounted cost is 80% of 750. That's 0.8*750=600. Because when the price is discount 20%, that means 20% is taken off. So 80% remains.

b: the profit is 792-600=192. This is 192/600*100= 32% profit.

c: she took 20% of the price off. If this means that she took $117 off, then the original price was 117/0.2=$585

d: She purchased it for $(468/1.3) = $360.
explanation: let the original price = x
We know that 468 = x + 0.3x = 1.3x
So, x = 468/1.3=360

Find the smallest power of 10 that will exceed M. Let M = 118,526.65902.
zavuch27 [327]

Answer:

The smallest power of 10 that will exceed M is 10^{6}.

Step-by-step explanation:

We can use the following approach to determine the smallest power of 10 that will exceed M. We can transform that number into scientific notation, which is of the form:

x.y \times 10^{n}, \forall \,x,y\in \mathbb{N}

Where:

x - Integer part, formed by a digit, which is of the highest order.

y - Decimal part, formed by a digit onwards.

n - Power grade.

The smallest power of 10 that will exceed M is 10^{n+1}

If M = 118,526.65902, then, the power grade is number of spaces that dot must be moved leftwards. In this case, dot must be moved 5 spaces on the left. The integer part is 1 and the decimal part is 1852665902. Then, the value of M in scientific notation is:

M = 1.1852665902\times 10^{5}

Then, the smallest power of 10 that will exceed M is 10^{6}.

Lesechka [4]

Answer:

10.5 %

<u>Skills needed: Financial Math Essentials</u>

Step-by-step explanation:

1) First, before getting started, let's assume the price of the product is x. This variable will be used a lot throughout the problem (x).

2) Marking a price above means increasing the price in order to make money off of the purchased product. When raising something by y percent, the new price would be x + \frac{y}{100}*x.

---> In this case, the price increased by \textbf{30} percent.

This means that it would be: x+\frac{30}{100}x = x+0.3x=1.3x

New price is: 1.3x

3) The shopkeeper is then offering a \textbf{15} percent discount off of this marked price. When offering a b percent discount price, the new price (with discount), expressed algebraically is: a-\frac{b}{100}a

---> the expression above simplifies to (1-\frac{b}{100})a

In this case, a=1.3x, b=15

---> (1-\frac{15}{100})*1.3x = (1-0.15)*1.3x=0.85*1.3x=1.105x

This means that x, with discount, has been raised \textbf{10.5 percent}.

10.5 % is the profit percent

(The profit percent being the final marked up price - purchased price)
