Sarah has two part-time jobs and needs to earn at least $300 total per week. Job A pays her $10 an hour and job B pays $7.50 an hour. Write an inequality that represents this scenario. Name and label your variables, such as Job A= x.
Job A: X hours/wk.
Job B: Y hours/wk.
10x + 7.5y => $300
job B:
Let's name and label our variables:
Job A = x (representing the number of hours worked at Job A)
Job B = y (representing the number of hours worked at Job B)
Now, let's determine the weekly earnings for each job:
Job A: $10/hour * x hours = $10x
Job B: $7.50/hour * y hours = $7.50y
Since Sarah needs to earn at least $300 in total per week, we can write the inequality as follows:
$10x + $7.50y ≥ $300
So, the inequality representing this scenario is:
10x + 7.50y ≥ 300
