By applying the concept of <em>finite</em> sum and the properties of the series, we conclude that the <em>finite</em> sum p = \sum \limit_{x=1}^{3} 2^{x}+ 2 is equal to the value of 34.

<h3>How to find the result of finite sum</h3>

Let be a sum of the form p = \sum\limits_{i= 1}^{n} a_{i}, where n represents an integer. This kind of sum represents a <em>finite</em> sum, whose <em>expanded</em> form is presented below:

p = a₁ + (a₁ + a₂) + (a₁ + a₂ + a₃) + ... + (a₁ + a₂ + a₃ + ... + aₙ₋₁ + aₙ)     (1)

If we know that p = \sum \limit_{x=1}^{3} 2^{x}+ 2, then the result of the finite sum is:

p = (2 + 2¹) + (2 · 2 + 2¹ + 2²) + (3 · 2 + 2¹ + 2² + 2³)

p = 4 + (4 + 6) + (6 + 14)

p = 4 + 10 + 20

p = 34

By applying the concept of <em>finite</em> sum and the properties of the series, we conclude that the <em>finite</em> sum p = \sum \limit_{x=1}^{3} 2^{x}+ 2 is equal to the value of 34.

The drama club is selling T-shirts and caps to raise money for a spring trip. The caps sell for $5.00 each, and the T-shirts sel
Zinaida [17]

The required inequality is 5x+10y\geq 500

<em><u>Solution:</u></em>

Given that,

Cost of 1 cap = $ 5

Cost of 1 t-shirt = $ 10

Let "x" be the number of caps sold

Let "y" be the number of t-shirts sold

The drama club needs to raise at least $500.00 for the trip

Based on this information, we can frame a inequality as:

number of caps sold x cost of 1 cap + number of shirts sold x cost of 1 shirt \geq 500

Which means,

x \times 5 + y \times 10\geq 500\\\\5x + 10y\geq 500

Here we used "greater than or equal to" symbol , because club needs to raise at least $ 500

They can raise 500 or more than $ 500 also

Thus the required inequality is 5x+10y\geq 500
