Answer:
1.5
Step-by-step explanation:
Given the pair of points on the table.
Now the formula for slope,
To calculate the slope we only require two pair of points.
Let us take:
The slope of the linear function represented by the values in the table is 1.5.
Note: You can use any two set of values. The result will be the same.
Answer:
Step-by-step explanation:
Given that the change is -13/10 in 10 seconds
Here, you can write this statement as;
10s = -13/10
30s=?----------------perform cross-multiplication
(-13/10 * 30 ) /10
Ok, so we know it costs $1.10 to make a pin, so the cost of making all 1000 pins must have been:
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;
So 390 pins sold at $3 each comes to
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;
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
Which to one decimal place is 65.5% profit.
Hope this helped.
