Evaluate S5 for 300 + 150 + 75 + … and select the correct answer below. 18.75 93.75 581.25 145.3125

Answers

It's a geometric sequence.

300, 150, 75,... \n \n a_1=300 \n r=(a_2)/(a_1)=(150)/(300)=(1)/(2) \n \n S_n=(a_1 (1-r^n))/(1-r) \n \Downarrow \n S_5=(300(1-((1)/(2))^5))/(1-(1)/(2))=(300(1-(1)/(32)))/((1)/(2))=(300 * (31)/(32))/((1)/(2))=(75 * (31)/(8))/((1)/(2))=((2325)/(8))/((1)/(2))=(2325)/(8) * 2= \n=(2325)/(4)=581 (1)/(4)=581.25

The answer is 581.25.

we have that

300 + 150 + 75 +...

Let

a1=300\n a2=150\n a3=75

we know that

(a2)/(a1) =(150)/(300) \n\n (a2)/(a1)=0.5 \n \n a2=a1*0.50

(a3)/(a2) =(75)/(150) \n\n (a3)/(a2)=0.5 \n \n a3=a2*0.50

so

a(n+1)=an*0.50

Is a geometric sequence

Find the value of a4

a(4)=a3*0.50

a(4)=75*0.50

a(4)=37.5

Find the value of a5

a(5)=a4*0.50

a(5)=37.5*0.50

a(5)=18.75

Find S5

S5=a1+a2+a3+a4+a5\n S5=300+150+75+37.5+18.75\n S5=581.25

therefore

the answer is

581.25

Alternative Method

Applying the formula

S_n=(a_1 (1-r^n))/(1-r) \n\na_1=300 \n r=(1)/(2)\n\n S_5=(300(1-((1)/(2))^5))/(1-(1)/(2))\n\n=(300(1-(1)/(32)))/((1)/(2))\n\n=(300 * (31)/(32))/((1)/(2))\n\n=(75 * (31)/(8))/((1)/(2))\n\n=((2325)/(8))/((1)/(2))\n\n=(2325)/(8) * 2\n\n=(2325)/(4)\n\n=581 (1)/(4)\n\n=581.25

therefore

the answer is

581.25

An article retails for $37.50. The city sales tax is 6%, and the federal excise tax is 8%. How much does the article cost altogether?

Answers

Answer:

Total cost of the article altogether is $42.75 .

Step-by-step explanation:

As given

An article retails for $37.50.

The city sales tax is 6%, and the federal excise tax is 8%.

6% is written in the decimal form

= (6)/(100)

= 0.06

Price of city sales tax = 0.06 × Article cost

                                    = 0.06 × 37.50

                                    = $ 2.25

8% is written in the decimal form

= (8)/(100)

= 0.08

Price of federal excise tax  = 0.08 × Article cost

                                             = 0.08 × 37.50

                                             = $ 3

Thus

Total cost of the article altogether = Article cost + Price of city sales tax + Price of federal excise tax

Putting all the values in the above

                                                         = $ 37.50 + $2.25 + $3

                                                         = $ 42.75

Therefore the total cost of the article altogether is $42.75 .
Hey:-)

Let the cost of article be x
37.50=x+0.06x+0.08x
Solve for x
X=32.9
