Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $775 from a combination of $5.00 quick washes and $8.00 premium washes. This system of equations models the situation. x + y =125 5x + 8y = 775

  (1)

  (2)

We can solve for y from equation (1) and we got:

  (3)

And replacing (3) into (2) we got:

And solving for x we got:

And solving for y from (3) we got:

And the solution would be x = 50 and y =75

Step-by-step explanation:

For this problem we have the following system of equations:

  (1)

  (2)

We can solve for y from equation (1) and we got:

  (3)

And replacing (3) into (2) we got:

And solving for x we got:

And solving for y from (3) we got:

And the solution would be x = 50 and y =75

3

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
