The answer is C. $5,355
In order to find this amount you need to find how much he makes in each month individually. We'll start with month one where he sold $13,500 worth of software. Since that number is under $20,000 we know that he makes 10%. So to find his earnings, we simply multiply the told sold by the percentage.
$13,500 * 10% = $1,350
Now we need to find the amount for month two. Since he sold $26,700, which is more than $20,000 we know that he gets the 15% of the amount sold. Similarly to last time, we'll multiply the two together.
$26,700 * 15% = $4,005
Now you can combine the two of them to find the overall amount.
$1,350 + $4,005 = $5,355
Answer:
(A) 125 scoops
(B) 31 scoops
Step-by-step explanation:
The volume of a cup in terms of radius and height is ...
V = (1/3)πr²h
The radius is half the diameter, so the volume in terms of diameter is ...
V = (1/3)π(d/2)²h = (π/12)d²h
The number of cups it takes to empty the sink will be the sink volume divided by the cup volume, so will be ...
n = (4000π/3)/((π/12)d²h)
n = 16000/(d²h)
__
(A) The number of cups required of diameter 4 and height 8 is ...
n = 16000/(4²·8) = 125
125 scoops are required to empty the sink
__
(B) The number of cups required of diameter 8 and height 8 is ...
n = 16000/(8²·8) = 31.25 ≈ 31
31 scoops are required to empty the sink
The answer is 70 because if you multiply the money she spends by the number of days you get 15. Then subtract 15 from 85 and you will get 70
