How many solutions for linear equation 3x + 5y = 25 can be found so that −20 &lt; y &lt; 10, and x is an integer?
ch4aika [34]

Elan Coil [88]

Answer:the function representing profit, P = 3n + 200

The revenue, or the amount he receives for selling n jars, can be represented by the function R = 5n.

Profit = revenue - cost or expenses.

Therefore,

The function representing Dominic's profit, P, for selling n jars of salsa will be

P = 5n - 2n + 200 = 3n + 200
