Ok, so we know it costs $1.10 to make a pin, so the cost of making all 1000 pins must have been:
1.10 \times 1000 = 1100
We know that 35% of the pins, hence 350 pins, were given to charity (we assume this means donated for free), and so the company sold 650 pins.

60% of these we sold at $3 each;
0.60 \times 650 = 390
So 390 pins sold at $3 each comes to
390 \times 3 = 1170
So the company has already made $1170.

The other 40% of the 650 remaining pins (260 pins) were sold at $5 for 2. We assume from the question that they were only sold in pairs and were all sold, so we can essentially figure out that 130 pairs were sold at $5 each;
130 \times 5 = 650
So the company has sold the pins for $650 + $1170 = $1820

This means that the company has made
$1820 - $1100 = $720 as profit

So the percentage profit earned (profit/cost times 100%) would be
\frac{720}{1000}  \times 100 = 65.4545....
Which to one decimal place is 65.5% profit.

Hope this helped.

Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%. Its current value is $2,000. The equ
irga5000 [103]

I hope the equation will be 2000=16000(1-r)^t because t is missing in the equation which we need to find.

Given rate: r= 35%= 0.35.

So, first step is to plug in 0.35 for r in the given formula to get the value of t.

Hence, the equation will be:

2000=16000(1-0.35)^t

2000=16000(0.65)^t (By subtraction)

2000/16000= 16000(0.65)^t /16000 (Dividing each sides by 16000)

0.125 = 0.65^t (By simplifying).

log 0.125 = log 0.65^t (Taking log each sides to isolate t).

log 0.125 = t log 0.65 (By applying the log property).

\frac{log 0.125}{log 0.65} =t (Dividing each sides by log 0.65)

-0.903/-0.187 =t

t= 4.83

t= 5 ( Rounded to nearest integers)

So, Devon's car is 5 years old.

PLEASE HELP ME WITH THIS QUESTION FOR MATH!!!!!!!!!!!!!!!!!
kozerog [31]

Answer:

MON = 130°

Step-by-step explanation:

LOM + MON = 180°

In other words

4z + 30° + 8z + 90 = 180°

12z + 120 = 180

60 = 12z

z = 5

5 x 8 = 40 + 90 = 130°
