A businessman is paid $12 per hour and $10 for each sale he makes. He wants to earn more than $250 in an 10-hour work period. Write an inequality that represents the number of sales, x, the businessman must make in an 10-hour period to earn more than $250.

What is the least number of sales he must make to reach his goal?

Multiply hotly rate by hours worked, he want to work 10’hours so 12 x 10 =120

Add that to number of sales x amount earned per sale: 10s

Now you have 120 + 10s

He wants to earn at least 250:

120 + 10s >= 250

Now solve for a

Subtract 120 from both sides:

10s >= 130

Divide both sides by 10:

S >= 13

Minimum sales need to be 13

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

answer: 2530

hope this
