Can someone help me understand this: Cindy works in a cake shop and earns $42 per day. She earns an extra $4 for each cake she sells. If Cindy wants to earn at least $50 per day, which inequality shows the minimum number of cakes, n, that she should sell?
ok what did u understand so far
I understand she works at a cake shop ..
lol ok what did u understand about her earning are u stuck somewhere in this part?
Well I have to find the answer, but I don't understand the overall question in which it wants you to do to find it
she gets a 42$ salary every day, and a bonus of $4 for each cake she manages to sell
alright I can understand that
the total earnings for a day is the base wage 42 plus 4 more for each cake Day Earnings = 42 + 4*(#cakes) she also wants that to be at least 50 dollars (greater or equal to 50
I think I get it now
k
she would need to sell four but my answer choices are out of 42 + 4n ≥ 50, so n ≥ 4 42 + 4n ≤ 50, so n ≤ 4 That's what im not understanding I guess
@DanJS
@baru
she would need to sell 2
Now im confused again
if she sells one cake, how much is her earnings for the day?
4$
earns 42, wants 50 or more, 2 cakes will take her to exactly 50, so at least that
4$ is the bonus
so it would be 42 + 4n ≤ 50, so n ≤ 2
no she wants at least 50 per day greater or equal to 50
you just have the inequality the wrong way
so it goes the other way?
yeah she wants her total earned money to be 50 or more dollars Total Earned \[Earned \ge $50\]
thanks
this one is easy to look and see if you set up right, she starts at $42 earned, and wants at least $50, each cake will earn her $4 more
42 + 2 cakes sold is the minimum
