Jennifer makes keychains and sells them online. she makes a profit if $3.00 per key chain but she has to pay $5.00 to paypal for using the app. how many keychains would she need to sell to make at least $375 in one day? write an inequality that represents this scenario and solve it. you must show your work to get credit.

number of key chains Jennifer needs to sell > 123.3

Step-by-step explanation:

We are given that Jennifer makes key chains and sells them online with a profit of $3.00 per key chain and has to pay $5.00 to PayPal for using the app.

We need to find out how many key chains Jennifer needs to sell to make a profit of at least $375.

Firstly, we will subtract $5 from $375 so we are left with $370.

Then we will divide $370 by 3 to get:

or

Therefore, number of key chains Jennifer needs to sell > 123.3.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
