Answer:
<h2>12.1% profit</h2>
Step-by-step explanation:
Given data
total eraser= 87
cost =$3 each
Total cost of eraser= 87*3= $261
she sold 63 at $3.5
1. sales made for the 63= $220.5
2 sale made for the remaining= 87-63=24
24*3=$72
Total sales made = 220.5+72=$292.5
her profit= sales-cost
profit= 292.5-261=$31.5
therefore the percent profit is
=31.5/261*100
=0.12*100
=12.1%
Answer:
the desired equation is y = x + 4.
Step-by-step explanation:
Slope is defined as m = rise over run. Run is the change (usually an increase) in x, and rise an increase or decrease in y.
We see, in the table, that if x increases from 1 to 6 (a 'run' of 5), y increases from 5 to 10 (a 'rise' of 5). Thus, it's immediately apparent that the slope is m = rise / run = 5 / 5, or just 1.
Using the slope-intercept form of the equation of a straight line, y = mx + b, and the point (1, 5), we calculate b:
5 = 1(1) + b, or b = 4.
Therefore the desired equation is y = x + 4.
The format of a line equation is y = mx + b
When two lines are parallel, their 'm' variables are equal.
Knowing this, the unknown line equation, so far, would look like this:
y = 9x + b
Since we know that the line equation goes through the point (2, 7)
7 = 18 + b
b = -11
y = 9x - 11
