During the summer, Jody earns $9 per hour babysitting and $10 per hour doing yard work. This week she worked 34 hours and earned $410. If x represents the number of hours she babysat and y represents the number of hours she did yard work, which system of equations models this situation?

1 answer

To model the situation with a system of equations, we need to consider the information provided:

  1. Jody earns $9 per hour babysitting and $10 per hour doing yard work.
  2. She worked a total of 34 hours.
  3. She earned a total of $410.

Let:

  • \( x \) = number of hours babysitting
  • \( y \) = number of hours doing yard work

From the information given, we can set up the following two equations:

  1. The total hours worked equation: \[ x + y = 34 \]

  2. The total earnings equation: \[ 9x + 10y = 410 \]

Thus, the system of equations that models this situation is:

\[ \begin{cases} x + y = 34 \ 9x + 10y = 410 \end{cases} \]
