See picture below. What is the difference between 4∑n=1 2n+1 and 4∑i=1 (2i+1)?
kondor19780726 [428]

Answer:

3

Step-by-step explanation:

\sum 2n+1= \boxed{\big( \sum_{i=1} ^{4}2n \big) +1}

And,

$ \sum (2i+1)= \sum (2i)+ \sum_{i=1} ^{4} (1) $

$=\sum_{i=1} ^{4}(2i) + 1+1+1+1 $

$=\boxed{\Big(\sum_{n=1} ^{4}(2n)\Big) +4}.... \text{Variable in Summation doesn't matter}$

Hence the difference is 3.

It costs the school band SS dollars per sandwich that they make. The band sells each sandwich for 20\%20% more than it costs to
Annette [7]

Money Required for making 1 Sandwich that is Cost Price of 1 Sandwich = S Dollar

Selling Price of 1 Sandwich = 20 % more than Cost Price S

                    = S + 20 % of S

                     = \frac{20S}{100}+S=\frac{120S}{100}

                     =$ 1.20 S

                      = $(S + 0.20 S)

Selling Price of 73 Sandwiches = $ 73 (S + 0.20 S)

The expression $73(S+0.2 S) →→  Selling Price of 73 Sandwiches
