An increase is generally regarded as being positive. If units are dollars, an increase of $15 can be represented by the integer +15.
__
<em>Additional comment</em>
If units are dimes, then the number would be +150. So, you see, <em>the units are important </em>to know.
It also depends on <em>what is increasing</em> and what is being represented by the integer. If it is an increase in debt, then the change in net worth might be -15.
Answer:
∠EFC and ∠DCF
∠BCF and ∠GFC
Step-by-step explanation:
The cash payment for the article is RS. 2,260.
A discount reduces the price of an item. The article becomes cheaper after the discount.
Cost of the article after the RS. 20 discount = RS. 2020 - 20 = RS 2000
VAT means value added tax. VAT increases the price of an item. The cost of the article increases by 13% after the VAT is levied,
Cost of the article = (100 + 13%) x 2000
1.13 x 2000 = RS 2,260.

The sum of a geometric series is given by:
Sn=[a(r^n-1]/(r-1)
the nth term is given by
an=ar^(n-1)
From the information given:
a1=0.28, r=6
the sum of the first 5 terms will be:
s₅=[0.28(6^5-1)]/(6-1)
s₅=[0.28(7776-1)]/5
s₅=2177/5
s₅=435.4
we have
One way to use mental math is to add to both and
so
therefore
the answer is
