Answer:  z = 247.5

Step-by-step explanation:

4.8/2z+15=0.2/5 To eliminate the denominators, multiply both sides by their reciprocals.

2z(5)(4.8/2z+15)=2z(5)(0.2/5)  Denominators "cancel." Distribute 5(4.8 + 15)

24 + 75 = 2z(0.2)    Simplify: Add  24+75=99 and Multiply 2z×0.2= 0.4z

99 = 0.4z .  Divide both sides by 0.4

99/0.4 = 0.4z/0.4 .   0.4  "cancels" on the right. dividing by a decimal is like multiplying by its reciprocal, 10/4 × 99

Use the following information for problems 1 – 3. Suppose you sign a contract for an annual salary of $50,000 with a guaranteed
erik [133]

Initial salary =  $50,000 .

Rate of raise = 5% each year.

Therefore, each next year salary would be 105% that is 1.05 times.

5% of 50,000 = 0.05 × 50000 = 2500.

Therefore raise is $2500 each year.

According to geometric sequence first term 50000 and common ratio 1.05.

Applying geometric sequence formula

a_n = ar^{n-1}

1) a_n = 50000(1.05)^{n-1}

2) In order to find salary in 5 years we need to plug n=5, we get

a_5 = 50000(1.05)^{5-1}= 50000(1.05)^4

= 50000(1.21550625)

<h3>=$60775.3125.</h3>

3) In order to find the total salary in 10 years we need to apply sum of 10 terms formula of a geometric sequence.

S_n = \frac{a(1-r^n}{1-r}

Plugging n=10, a = 50000 and r= 1.05.

S_10 = \frac{50000(1-(1.05)^{10}}{1-1.05}

S_10 = \frac{50000(0.050)^{10}}{0.05}

= 628894.62678.

<h3>Therefore , you will have earned $ 628894.62678 in total salary by the end of your 10th year.</h3>
