Answer:

$y=220-15x$

Step-by-step explanation:

Let x represent the number of times Giselle uses the athletic club and y represent money left in account.

We have been given that each time she uses the club, $15 is deducted from the account. The amount used after using the club after x times would be $15x$ .

We are also told that Giselle pays $220 in advance on her account at the athletic club.

The money left in account after x uses of athletic club would be money in account initially minus amount used for using the club x times.

$y=220-15x$

Therefore, our required equation would be $y=220-15x$ .

Tacoma's population in 2000 was about 200 thousand, and has been growing by about 8% each year. If this continues, what will Tac

Brums [2.3K]

Answer: The population will be 408,000 people.

Step-by-step explanation:

So in 2000 there were 200,000 people and it started to grow 8% every year so up to 2013.

so find 8% of 200,000 and then multiply it by the the number of years.

8% * 200,000 = 16,000

Find the difference between the years.

2013 - 2000 = 13 years

13 * 16000 = 208000 This is the amount of new people from 2000 to 2013 so add it to the original population.

208,000 + 200,000 = 408,000

A gift box has a volume of 450 cubic inches. The width of the box is 4 inches less than the length. The height is twice the widt

VashaNatasha [74]

Answer:

width = 5 in

length = 5+4=9 in

height = 2(5)= 10 in

Step-by-step explanation:

A gift box has a volume of 450 cubic inches.

Let 'w' be the width of the box

The width of the box is 4 inches less than the length.

$length = w+4$

The height is twice the width.

$height = 2 \cdot width$

height = 2w

Volume of box = length times width times height

$V=(w+4)(w)(2w)$

$450=(w+4)(w)(2w)$

$450=2w^3+8w^2$

$2w^3+8w^2-450=0$

$\quad 2\left(w-5\right)\left(w^2+9w+45\right)=0$

$w-5=0$

w=5

$\quad\left(w^2+9w+45\right)=0$ , this gives two complex values

so width = 5

length = 5+4=9

height = 2(5)= 10

A Shopkeeper

Sergio [31]

Answer:

The cost of bicycle is Rs1000

Step-by-step explanation:

Let x be the cost of bicycle

Total profit gained by the shopkeeper by selling at labelled price = 20%

Suppose he sell the bicycles at at 5% discount

Which means that the total profit he learn after discount will be:

20% -5% = 15%

The shopkeeper earns a profit of 15% if he sells at discount.

Profit gained by shopkeeper is:

15% of x = 15/100 · x

15% of x = 0.15x

Thus the profit gained will be 0.15x. As profit gained is equal to 150, we can say that

0.15x = 150

x = 1000

The cost of bicycle is Rs1000
