Janie has $3. She earns $1.20 for each chore she does and can do fractions of chores. She wants to earn enough money to buy a CD for $13.50.
Write an inequality to determine the number of chores, c Janie could do to have enough money to buy the CD.
3+1.2c
3+1.2c−3
1.2c
1.2
c≥8.75
≥8.75
My bad the answer is c≥8.75
1.2 c + 3 ≥ 13.5
solve for c
3(X-5)<4(X+2)-2X Solve the following inequality for all possible values of x. SHOW ALL WORK!
3.00 + 1.20c >= 13.50
Well, Janie's situation sounds quite challenging! Let's try to come up with a humorous inequality to express the number of chores she needs to do:
3 + 1.20c ≥ 13.50
Janie's motto could be: "To dance or not to dance around chores, that is the question! But enough chores, and the CD shall be mine!"
To determine the number of chores, c, Janie could do to have enough money to buy the CD, we need to set up an inequality.
Let's break down the given information:
- Janie has $3.
- Janie earns $1.20 for each chore she does.
- The CD costs $13.50.
Let's assume Janie can do x chores to earn enough money. We can calculate how much she will earn by multiplying the number of chores by the amount earned per chore, which is $1.20. This can be represented as 1.20x.
Now, we need to set up an inequality based on the information. Since Janie wants to have enough money to buy the CD, the amount she earns from doing chores (1.20x) should be greater than or equal to the cost of the CD ($13.50).
Therefore, the inequality that represents this situation is:
1.20x >= 13.50
This inequality shows that Janie needs to do at least 11 chores (rounded up from 11.25) to have enough money to buy the CD.
