Citrus2011 [14]

Answer:

925

Step-by-step explanation:

In order to solve this summation formula, you need to first understand what it means. The summation symbol is tell you to add the terms in a sequence. Below the summation sign, there is a variable and number; the variable n is the index of summation and the number 1 is the lower limit of summation or the first value of the sequence. The number 25 above the summation sign is the upper limit (so there would be 25 terms, with the first being 1). The polynomial to the right of the summation symbol represents the explicit function for each term. For example, using this, the first term would be (3(1) - 2) and the second (3(2) - 2) and so on. This means the value of that equation is:

(3(1) - 2) + (3(2) - 2) + (3(3) - 2)... + (3(25) - 2)

One way to solve this is to write all 25 of the terms and add them, but since that's tedious, you can solve this by first doing the basic summation of 1 to 25 and then inputting that into the equation:

1 + 2 + 3... + 25 = (25 × 26)/2 (when the first number is one and the rate of change is 1, the sum of the terms in a sequence is (n*(n+1))/2)

= 325

Now, that you know what the sum of the sequence of terms 1 to 25 are, you can multiply this by the constant since if you break up the equation you would be multiplying 3 by 1 then 3 by 2 and so on until 25, or 3 × (1 + 2 + 3... + 25):

3 × 325 = 975

At this point, you just need to add (-2) × 25. You do this because since there are 25 terms, if you subtracted 2 each time, you would subtract 2 twenty-five times:

975 + ((-2) × 25)

= 975 - 50

= 925

schepotkina [342]

Answer:

Step-by-step explanation:

Given:

Brett orders 2 meatball,1 turkey,1 veggie party-size sandwiches.

Each sandwich costs the same amount.

The total amount cost of the sandwiches, including tax, is $54.36.

Question asked:

What is the cost of each sandwich including tax?

Solution:

Let cost of each sandwich including tax = x

<u>Total number of sandwich = 2 + 1+ 1 = 4</u>

<u><em>As each sandwich costs the same amount and total amount of cost of 4  sandwiches, including tax, is $54.36, the equation will be:-</em></u>

x+x+x+x=\$54.36\\4x=\$54.36

By dividing both sides by 4,

x=\$13.59

Thus, the cost of each sandwich including tax is $13.59
