Ryan is opening up a bookstore, where he sells both new and old books. He

Bas_tet [7]

Answer:

Ryan's revenue last month if he sold 16 new books and 25 old books

is $337.50.

Step-by-step explanation:

The number of old books sold by Ryan = 25

The cost of each old book = $5.50

⇒ Total amount earned by selling 25 old books = 25 x $5.50

= $137.5

The number of new books sold by Ryan = 16

The cost of each new book = $12.50

⇒ Total amount earned by selling 16 new books = 16 x $12.50

= $200

Hence Total amount earned by Ryan

= Amount earned by selling old books + Amount by selling new books

= $137.5 + $200

= $337.50

or, Total amount earned by Ryan = $337.50

Hence Ryan's revenue last month if he sold 16 new books and 25 old books is $337.50.

Last week at a festival, a man sold 5 times as many tie-dyed T-shirts as silk-screened shirts. He sold 210 shirts altogether.

Alexeev081 [22]

Answer:

The number of tie-dyed shirts is 175

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of tie-dyed T-shirts sold.

y is the number of silk-screened shirts.

He sold 210 shirts altogether.

This means that $x + y = 210$

Last week at a festival, a man sold 5 times as many tie-dyed T-shirts as silk-screened shirts.

This means that $x = 5y$ or $y = \frac{x}{5}$

How many tie-dyed shirts did he sell?

This is x.

$x + y = 210$

$x + \frac{x}{5} = 210$

$\frac{5x + x}{5} = 210$

$6x = 210*5$

$x = \frac{210*5}{6}$

$x = 175$

The number of tie-dyed shirts is 175

What’s the slope intercept equation that passes through the points (0,2) and (4,-1)

Kobotan [32]

The slop-intercept form:

$y=mx+b$

m - slope

$m=\dfrac{y_2-y_1}{x_2-x_1}$

b - y-intercept

We have (0, 2) and (4, -1).

Substitute:

$m=\dfrac{-1-2}{4-0}=\dfrac{-3}{4}=-\dfrac{3}{4}$

(0, 2) → y = 2 is y-intercept. Therefore b = 2.

Answer: $y=-\dfrac{3}{4}x+2$
