Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
The sum of the hours he worked washing cars (x) and the hours he worked walking dogs(y) will be equal to the total hours worked (13)
For the second equation the product of the number of hours he worked washing cars(x) and the price per hour ($10) plus the product of the number of hours he worked walking dogs (y) and the price per hour ($9) will be equal to the total amount earned (122)-
So, the system of equations is:
Where:
x: number of hours Jose worked washing cars
y: number of hours Jose worked walking dogs

Tips with decimals....
Our decimal system gives us the flexibility to write numbers as large or
small as we like. The key to the decimal system is the decimal point. Anything
on the left of the decimal point represents a whole number, anything on the
right of the decimal represents less than one (similar to a fraction). Going
from left to right, the value of each place on the right of the decimal point is
1/10 the value of the place on the left. Good luck!
