Pete earns $8.50 per hour plus tips. On Tuesday, he received $16 in tips. How many hours did Pete work if he earned a total of $50 on Tuesday?

Answer : Pete worked 4 hours

Explanation: Since Peter earns 8.50 an hour we don’t know how many hours he worked so we use the variable x to substitute the hours since we don’t know them then since he got 16 dollars we add them so the equation so far is 8.50x+16 then they ask how many hours he works for a total of 50 dollars so we make the equation 8.50x+16=50 we subtract 50-16 then divide to get x=4 and that is how we got are answer have a nice day (:
