Question

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 Solve the system to answer the questions. How many premium car washes were ordered? How many quick car washes were ordered?

Answer 1

Answer:

he two equations are:

 x+y= 25 and

5x+8y=775

Where, x is the number of quick car washes and y is the number of premium car washes.

Multiplying the first equation by -5 we have:

(-5) * [x+y=125]

= -5x-5y =-625

Now adding this to the second equation and then solving for y, we have:

3y=150

y= 150/3

y=50

Now, taking y = 50 and putting it in any one of the original equations (let's put in the first one) will give us x.

x+y= 125

x+50=125

x= 125-50

x=75

Hence, there was 50 premium car washes and 75 quick car washes.
