Math Problem Statement

Aisha is working two summer jobs, making $7 per hour babysitting and $8 per hour landscaping. Last week Aisha worked 2 more hours babysitting than hours landscaping and earned a total of $134. Write a system of equations that could be used to determine the number of hours Aisha worked babysitting last week and the number of hours she worked landscaping last week. Define the variables that you use to write the system.

Solution

To solve this problem, let's define our variables and set up a system of equations based on the information given.

Step 1: Define the Variables

  • Let xx represent the number of hours Aisha worked landscaping last week.
  • Let yy represent the number of hours Aisha worked babysitting last week.

Step 2: Set Up the Equations

  1. Equation based on the time worked difference:

    • Aisha worked 2 more hours babysitting than landscaping, so: y=x+2y = x + 2
  2. Equation based on total earnings:

    • Aisha earns $7 per hour babysitting and $8 per hour landscaping, and her total earnings were $134. Therefore: 8x+7y=1348x + 7y = 134

System of Equations

So, the system of equations is:

y = x + 2 \\ 8x + 7y = 134 \end{cases}$$ This system can be used to solve for $$x$$ and $$y$$, which represent the hours worked landscaping and babysitting, respectively. Would you like me to solve this system? Let me know if you have any questions. --- Here are some related questions to explore: 1. How many hours would Aisha need to work if she only did babysitting to earn the same amount? 2. If Aisha's hourly rate for landscaping increased to $9, how would her total earnings change for the same hours? 3. What if Aisha worked equal hours in both jobs but still earned $134? How would the hours be distributed? 4. How would the system of equations change if she worked 3 more hours babysitting than landscaping? 5. What if Aisha’s total earnings were $150 instead? How would this affect her hours? **Tip:** When creating equations from word problems, carefully translate each piece of information to form logical relationships between variables.
