Question

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.

Answer 1

375/3 = 125
125÷5 = 25
125-25 =100
key chains = 100

Answer 2

number of key chains Jennifer needs to sell > 123.3

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:

`(370)/(3) =123(1)/(3)` or
`123.3`

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