3.2.AP-10 Question Help
The Stock Market Nadia is a stockbroker. She earns 4% commission each week. Last week, she
earned $288 in commission. How much were her total sales? If she earns $14,000 in commission,
how much did she sell last week?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
