Answer:
rs 200
Step-by-step explanation:
Let cost price = x
At 30% profit; marked price of radio is 30% of x = (100% + 30%) = 130%x
Discount = rs 3%
Profit made = 30
Hence,
Marked price - discount = cost price + 30
130%x - 30 = x + 30
1.3x - 30 = x + 30
1.3x - x = 30 + 30
0.3x = 60
Divide both sides by 0.3
0.3x / 0.3 = 60/ 0.3
x =
1.3x / 1.3 = 60 / 1.3
x = 200
Hence, cost price = rs 200

Answer: 
Step-by-step explanation:
The slope of line l is
Since parallel lines have the same slope, the slope of the line we need to find is -2.
Substituting into point-slope form,
To convert 8.0464x10^-7 from scientific notation to decimal notation, you need to move the decimal point to the left seven times.
Therefore the answer is:
0.00000080464
Note: 10^-7 equals 1/10^7
8.0464x10^-7 can be rewritten as:
8.0464/10^7 (i.e. divide 8.0464 by 10000000)
which results: 0.00000080464
$34.66
9.99 x 4 = $39.96
minus 20% is 31.96 unless you round up which would be $31.97
6.75% sales tax on 31.96 is $2.1573
6.75% sales tax on 31.97 is $2.1579
