David is a car salesman. he earns a salary of $750 a month, plus a commission of $3,500 per month. write an inequality for the number of sales he needs to make to earn his minimum. let c represent the number of cars sold per month

Step-by-step explanation:

0C sold is equal to $750.

1C sold is equal to $750+300= 1050

2C sold is equal to $750+300×2 = 1350

3C sold is equal to $750+300×3= 1650

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
