Step-by-step explanation:
Answer:
-8 < x, the answer is B
Step-by-step explanation:
Since its starting from -8 and your going to the greater side of the numberline teh variable will be greater than -8, whenever the circle is filled it just means greater than or equal to depending on which side its going. If its filled in, it means that its greater than or equal to or less than or equal to depending on which side its going towards.
Reminder:
<--------------- Negative side/Lower -----------------------> Positive side/Greater
You factor out 2y from the situation
Answer:
13%
Step-by-step explanation:
the cost price of 1/3 of the sugar = 1/3 x 4500 = 1500
gain= x 100
let x = unknown selling price
(x - 1500) / 1500 = 0.1
to solve for x, multiply both sides of the equation by 1500
x - 1500 = 150
x = 1650
the selling price of the 1/3 of sugar that yielded a 10% gain is 1650
to determine the gain percent of the remaining sugar, the selling price of the remaining sugar has to be determined . Let the selling price be represented by a
Based o the information in the question and the previous solution, the following equation can be derived
{(a + 1650) - 4500} / 4500 = 0.12
Solve for a
Multiply both sides of the equation by 4500
a + 1650 - 4500 = 540
a = 3390 = selling price of 2/3 of the sugar
Percent gain that the 2/3 of the sugar should be sold can be determined by taking the following steps
first find cost price of the 2/3 of sugar = 2/3 x 4500 = 3000
gain = (3390 - 3000) /3000 = 0.13 = 13%
By definition we have that the compound interest formula is:
Where
A: amount
P: principal
r: interest rate (decimal)
n: number of times interest is compounded per year
t: time years
Substituting values we have:
