Call the number of hours babysitting
and the number of hours walking dogs
.
We know that she earns $6/hr for babysitting or
, and $5/hr walking dogs or
. We also know the total money is $43 and the total time is 8hours. Therefore:
To solve: First rearrange equation 1 to solve for either
or
(doesn't matter which, I'll use
):
Now substitute into equation 2:
and solve for
Now backsubstitute to solve for
:
