Since it is a conventional , mathematicl notation
A break even problem is found when you calculate starting a buisieness
so lets ssay you have to buy 3 coppy machines and each machine costs 2000 dollars,
the people who want to use your coppy machines have to pay $0.40 per page
so you have spent 6000 dollars already

Answer:
15n=135
Step-by-step explanation:
first, you need to know how much of the total amount is the money needed for soccer balls, to find this you take the amount of a soccer ball and multiple it by the amount of people
14×15=210

to get the amount of each jersey you take 135 and divide by the amount of people
135÷15=9
