Answer:the system of linear equations that represents the situation are
5x + 8y = 775 and x + y =125
Step-by-step explanation:
Let x represent the number of quick washes and let y represent the number of premium washes.
After washing 125 cars, this means that
x + y = 125 - - -- - - - - - -1
they made $775 from a combination of $5.00 quick washes and $8.00 premium washes. This means that
5x + 8y = 775 - - - - - - -2
Equation 1 and equation 2 are the system of linear equations that represents the situation.
