A worker wants to save enough money to buy new headphones, which cost $119. He makes $7 per hour at his
job. He wants to figure out the least number of hours he can
work to have enough money to buy the headphones. Write
an inequality and solve.

      Zachary is working two summer jobs, making $11 per hour lifeguarding and making $14 per hour clearing tables. In a given week, he can work no more than 17 total hours and must earn a minimum of $210. Also, he must work at most 14 hours clearing tables. If x represents the number of hours lifeguarding and y represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.

Step-by-step explanation:

The least amount of numbers that he can work at his job to have enough for the headphones he wants is 17 hours.

Step-by-step explanation:

To find the number of hours you could divide the cost of the headphones by the amount he earns each hour so you would do $119/ 7 to get 17 and then you could check your answer with multiplication by multiplying 7 * 17 to get 119 which shows that he has to work at least 17 hours to get the headphones he wants.

$119 / 7 = 17

17 * 7 = 119

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
