Answer:
13
Step-by-step explanation:
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
44% = 44/100 = 44 ÷ 100 = 0.44.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 44% of its value.
Percentage decrease = 44% × 13
New value = 13 - Percentage decrease
Answer: $1,842
Step-by-step explanation:
John wants to earn 25% of his investment of $50,000 which is:
= 25% * 50,000
= $12,500
He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:
= Expenses + Return
= 9,600 + 12,500
= $22,100
Rent per month is:
= 22,100 / 12
= $1,842
In the future, please post the full problem with all included instructions. After doing a quick internet search, I found your problem listed somewhere else. It mentions two parts (a) and (b)
Part (a) asked for the equation of the line in y = mx+b form
That would be y = -2x+9
This is because each time y goes down by 2, x goes up by 1. We have slope = rise/run = -2/1 = -2. This indicates that the height of the candle decreases by 2 inches per hour. The slope represents the rate of change.
The initial height of the candle is the y intercept b value. So we have m = -2 and b = 9 lead us from y = mx+b to y = -2x+9
----------------------------------------------------------------
Part (b) then asks you to graph the equation. Because this is a linear equation, it produces a straight line. We only need 2 points at minimum to graph any line. Let's plot (0,9) and (1,7) on the same xy grid. These two points are the first two rows of the table. Plot those two points and draw a straight line through them. The graph is below
