Question

The soccer team is selling key chains to raise money for the team. They ordered 100 key chains that sell for .25 each. There is a flat shipping rate of $8. The team sells the key chains for $2 each. With that information, I figured they made $33.00 selling the 100 key chains, BUT
I don't know how to write an inequality to find the fewest number of key chains, k, the team must sell to make a profit (more than $33.

Answer 1

cost = 100(.25) + 8 = 33
number sold ---- x
2n - 33 > 0
2n > 33
n > 16.5 , so they sell at least 17 chains, or
the fewest number they must sell is 17

if they sold all 100, their profit is 200 - 33 or $167

Am I missing something here ? looks pretty straightforward.
