Based on the terms of the invoice, the gross amount on the invoice and the date of payment, the cash discount is $19 and the net amount paid is $931.
<h3 /><h3>What is the cash discount?</h3>
The terms of the invoice are such that if the person pays within 10 days they get a 3% discount. If they pay in 15 days, they get a 2% discount.
The person paid on the 22nd after buying on the 8th so they qualify for the 2% for paying within 15 days.
The cash discount is:
= 2% x 950
= $19
The net amount paid is:
= 950 - 19
= $931

The given expression is the expansion of cos (a-b)
so we can simply calculate it as <span>cos(112-45)= cos 67</span>
Answer:
3.225 gram
Step-by-step explanation:
Given that :
Initial weight = 0.06g
Rate of increase, r = 10% = 0.1 per day
Weight gain after 6 weeks
For an exponential model. f(x)
f(x) = a(1 + r)^x
Where ; a = initial amount ; r = growth rate ; x = period
Our model becomes :
f(x) : 0.06(1 + 0.1)^x
f(x) = 0.06(1.1)^x
Number of days in 6 weeks = 6*7 = 42 = x
f(42) : 0.06(1.1)^42
= 3.285 gram
Hence, weight gain after 6 weeks :
(3.285 - 0.06) g = 3.225 gram
