1 answer:

8 0

Start of by trying to make 4w the subject of the equation. + 15 to each side making the equations 4w= 15+17, (15+17=32) 4w= 32 meaning that w= 8 because all you do is divide each side of the equation by 4 . HOPE THAT HELPS . if you need more help just shout me

Roy Gross is considering an investment that pays 7.6 percent, compounded annually. How much will he have to invest today so that

Debora [2.8K]

Answer: he should invest $16129 today.

Step-by-step explanation:

Let $P represent the initial amount that should be invested today. It means that principal,

P = $P

It would be compounded annually. This means that it would be compounded once in a year. So

n = 1

The rate at which the principal would be compounded is 7.6%. So

r = 7.6/100 = 0.076

The duration of the investment would be 6 years. So

t = 6

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years.

A = 25000

Therefore

25000 = P(1+0.076/1)^1×6

25000 = P(1.076)^6

25000 = 1.55P

P = 25000/1.55

P = $16129

A performer expects to sell 5,000 tickets for an upcoming concert. They want to make a total of $311, 000 in sales from these ti

Annette [7]

The price of one ticket is $ 62.2

<h3><u>Solution:</u></h3>

Given that a performer expects to sell 5000 tickets for an upcoming event

They want to make a total of $ 311, 000 in sales from these tickets

<em><u>To find: price of one ticket</u></em>

Let us assume that all tickets have the same price

Let "a" be the price of one ticket

So the total sales price of $ 311, 000 is obtained from product of 5000 tickets and price of one ticket

$\text {total sales price }=5000 \times \text { price of one ticket }$

$311000 = 5000 \times a\\\\a = \frac{311000}{5000}\\\\a = 62.2$

Thus the price of one ticket is $ 62.2

(5x-25)+(3x+9)=180 please answer right now

jok3333 [9.3K]

Answer:

$x=24.5\\$

Step-by-step explanation:

So we have the equation:

$(5x-25)+(3x+9)+180$

Combine like terms:

$(5x+3x)+(-25+9)=180$

Add:

$8x-16=180$

Add 16 to both sides:

$8x=196$

Divide both sides by 8:

$x=24.5\\$

So, our answer is 24.5 :)
