Answer:
x - 40
10 - 400
Step-by-step explanation:
I'm pretty sure the rule is x • 40 = y (or input • 40 = output)
This is the working but there are 2 other methods that can help you arrive to the same answer
Answer:
15%
Step-by-step explanation:
Let
Selling price = SP
Cost price = CP
If CP = 100
Profit = selling price - cost price
x% = SP - x% of 100
x% + 100x% = SP
SP = 100 (1 + x/100) (1)
If CP = 92
SP = 92 (1+ {x+10}/100)
Equate both SP
100 (1 + x/100) = 92 (1+ {x+10}/100)
100 + x = 92 + [{23/25} * (x+10)]
{2/25}x = 30/25
x = 30/25 ÷ 2/25
= 30/25 × 25/2
= 30/2
x = 15%
Multiplying the values given above we obtain a value of 0.01386. In scientific notation, 1.386 x 10^-2. <span>The </span>significant figures<span> of a number are </span>digits<span> that carry meaning contributing to its measurement resolution. From the multiplicand and the multiplier, the least number of significant significant figure would be one. Therefore, we write as
1.0 x 10^-2</span>
