shopkeeper sells one machine for 990 re at a profit of 10% and another machine for 1960 at a loss of 2%
Complete question :
shopkeeper sells one machine for 990 re at a profit of 10% and another machine for 1960 at a loss of 2%. What is his gain or loss percent
Answer:
1.72%
Step-by-step explanation:
Given that :
MACHINE 1:
Sales price = 990
Profit percent = 10%
The cost price of the machine (x) :
10% profit of x :
(100 + 10)% of x = 990
110% of x = 990
1.1x = 990
x = 990/1.1
x = 900
MACHINE 2:
Sales price = 1960
Loss on sale = 2%
Cost price (x) :
(100 - 2)% of x = 1960
98% x = 1960
0.98x = 1960
x = 1960/0.98
x = 2000
Total amount realized from sale = (990 + 1960) = 2950
Total cost of production = (2000 + 900) = 2900
Profit Made = (2950 - 2900) = 50
% profit:
(Profit / cost of production) * 100
(50 / 2900) * 100%
0.0172413 * 100%
profit % = 1.72
The profit made is 50
Cost price of first machine will be:
= 100/(100 + 10) × 990
= 100/110 × 990
= 100 × 9
= 900
Cost price for second machine will be:
= (100 - 2) × x = 1960
= 98% × x = 1960
= 0.98x = 1960
x = 1960/0.98.
x = 2000
The total cost price = 900 + 2000 = 2900
Total selling price = 990 + 1960 = 2950
Therefore, profit will be:
= Selling price - Cost price .
= 2950 - 2900
= 50

Chau rented a truck for one day. There was a base fee of $20.99, and there was an additional charge of 79 cents for each mile driven. Chau had to pay $130.80 when he returned the truck.
For how many miles did he drive the truck?
Answer:
Chau drove 139 miles
Step-by-step explanation:
Knowing how much Chau spent at the end makes the question much much easier. So what you want to do is take of the base fee ($20.99) off the final amount he had to pay.
$130.80 - $20.99 = $109.81
Now you divide $109.81 by the additional charge ($0.79)
Change the divisor (0.79) to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend (109.81) the same, 2 places to the right.
We then have the equations:
10981 ÷ 79 = 139.000
and therefore:
109.81 ÷ 0.79 = 139.000
Chau drove 139 miles.
What is the domain of the function
f(x)=1x-3
-3 when the range is {-6. 0, 9}?
Answer:
D : { -3, 3, 12}
Step-by-step explanation:
I would suggest substituting the range for the function and solving for x like so.
i.e -6 = 1x-3, -6 + 3 = 1x -3 + 3, -3 = x, x = -3.
0 = 1x - 3, 0 + 3 = 1x - 3 + 3, 3 = x, x = 3.
9 = 1x - 3, 9 + 3 = 1x -3 + 3, 12 = x, x = 12
