The soccer team collected $800 at a car wash fundraiser. they charged $5.00 for small vehicles and $10.00 for larger vehicles. the amount collected can be modeled by the equation 5x + 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. if the number of larger vehicles washed was 50, how many small vehicles were washed in total?

Answer with Step-by-step explanation:

The soccer team collected $800 at a car wash fundraiser.

The amount charged for small vehicles=$5.00  

and amount charged for larger vehicles=$10.00

Let x represents the number of small vehicles and y represents the number of larger vehicles.

Then, 5x + 10y = 800

Now, when y=50

5x+10×50=800

i.e. 5x+500=800

i.e. 5x=800-500

i.e. 5x=300

Dividing both sides by 5, we get

x=60

Hence, number of  small vehicles washed in total is:

60

2222222222222222222

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
