For 31 you need 6% OF 50 meaning you need to multiply. 50*0.06=3. The answer for 31 is 3.
To find 33 you need to divide 1 by 0.4 to find how much you need to multiply 28 by. 1/0.4= 2.5 then you need to do 2.5*28 which would equal 70. The answer for 33 is 70.
To find 35 you need to notice that it DECREASES in meaning the bigger number (20) would be the denominator of the fraction and 15 would be the numerator. Therefore the fraction would b 15/20 or 75% of 20 would equal out to 15.
Answer:
And on this case we can use the product rule for a derivate given by:
Where 
and 
And replacing we have this:
Step-by-step explanation:
We assume that the function of interest is:
And on this case we can use the product rule for a derivate given by:
Where and
And replacing we have this:
Set up a proportion
EA / EB = ED/ EC
16 / (5x + 2 + 16) = 12 / (12 + 24)
16/(5x + 18) = 12 / 36 Cross multiply
16 * 36 = (4x + 18)*12 Remove the brackets
576 = 48x + 216 Subtract 216 from both sides.
360 = 48x Divide by 48
360/48 = x
7.5 = x
The number of days that Aubrey can drive to stay in her budget is 5 days.
<h3>Inequality signs and their meanings</h3>
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
<h3>Equation that represents the question</h3>
Total amount that can be spent ≤ (cost to rent a car per day x number of days) + (cost per mile x total miles driven)
$130 ≤ ($22.15 x dd) + ($0.07 x 275)
<h3>Determination of the number of days that Aubrey can drive</h3>
130 ≤ ($22.15dd) + ($0.07 x 275)
130 ≤ $22.15dd + 19.25
130 - 19.25 ≤ $22.15dd
110.75 ≤ 22.15d
d ≤ 110.75 / 22.15
d ≤ 5
