Answer:
M = 3000n(20 - n) dollars.
Step-by-step explanation:
Given that, each machine sets up in one day.
Therefore, n number of machines will take n days to set up.
Now, there are 20 days' time to deliver all the t-shirts.
And the machines are turned on after all the n machines are set up.
So, all the n machines will work for (20 - n) days and producing each machine 200 shirts in one day, then one machine will produce 200(20 - n) number of t-shirts and n machines will produce 200n(20 - n) number of t-shirts in the remaining (20 - n) days.
Now, the selling price for each t-shirt is $15.
Therefore, the total amount of money M she will receive will be, M = 15 × 200n(20 - n) = 3000n(20 - n) dollars. (Answer)
Hello!
To find the minimum number of weeks Jakob will need to wait if he saved 35 dollars per week, we would need to create an inequality equation.
Since he needs to save at least 700 dollars, it can be represented by the the greater than or equal to symbol. Also, the variable x, will be used in this equation representing the number of weeks. Then, we can create an equation for this problem.
35x + 175 ≥ 700 (subtract 175 from both sides)
35x ≥ 525 (divide both sides by 35)
x ≥ 15
Therefore, Jakob will have to wait a minimum of 15 weeks in order to save at least 700 dollars for a new computer.
