Perry made $34,885 this year. If the inflation rate was 6.5 percent, how much was his salary actually worth? (purchasing power)
Allushta [10]
<h3>The salary of Perry if inflation is 6.5 % is $ 32617.475</h3>

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

Given that,

Perry made $34,885 this year

The inflation rate was 6.5 percent

To find: Salary worth if inflation rate was 6.5 percent

From given,

Inflation rate = 6.5%

Therefore,

Worth of salary due to inflation = 100 % - 6.5 % = 93.5 %

Money earned in this year by Perry = $ 34, 885

Therefore,

Worth of Perry salary due to inflation = 34,885 x 93.5%

\text{Worth of Perry salary due to inflation }= 34885 \times \frac{93.5}{100}\\\\\text{Worth of Perry salary due to inflation }= 34885 \times 0.935\\\\\text{Worth of Perry salary due to inflation }= 32617.475

Thus the salary of Perry if inflation is 6.5 % is $ 32617.475

Mice21 [21]

Answer:

x = 50°

130 and x are adjacent angles on a straight line and sum to 180° , so

x + 130° = 180° ( subtract 130° from both sides )

x = 50°

If it takes 1/2 day to write a report, how much will be completed after 1/4 of a day?
lana [24]

Answer:

You have completed only half in a 1/4 of a day

Step-by-step explanation:

think of it this way

lets say in half a day e.g at 12pm you finish the report

half of 12 is 6

so that would be a 1/4 of the day

100%=24 hours=whole day

50%=12 hours=half a day

25%=6 hours = quarter of a day

25% = 1/4

i hope this helps

A box contains 10 red , 3 blue, and 7 white balls , two balls are drawn at random from the box on after the other without replac
mestny [16]

Answer:

P(XX) = 69/190

Step-by-step explanation:

Given:

20 balls, 10R, 3B, 7W.

Two taken without replacement.

Find probability of two identical colours.

P(XX)

Solution:

We use the multiplication rule for the probability of each of the 2 draws

P(RR) = 10/20*9/19 = 90/380

P(BB) = 3/20*2/19 = 6/380

P(WW) = 7/20*6/19 = 42/380

Probability of drawing two identical coloured balls

P(XX) = (90+6+42)/380 = 138/380 = 69/190
