A group of students organized a car wash to raise money for a local charity. The students charged $8.00 for each car they washed. In 4 hours, they washed 16 cars. At that rate, how much money could they earn from washing cars for ten hours?

$320

Step-by-step explanation:

First, we can find how many cars they washed.

At 8 hours, they washed 32 cars, and since you still have two hours worth of cars to find, you can divide 16 by 2, and you get 8.

So in total, they washed 40 cars.

Now, you can multiply 40 by $8.00, and you get $320.

$320

Step-by-step explanation:

They charged &8.00 for each car. In 4 hours they washed 16 cars. This averages to 4 cars every hour. If they did this for 10 hours then you would multiply 10 by 4. That would equal 40 cars in total. If you multiply 40 by 8 you get 320

Hope this helped everyone:)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
