Answer: 4290 flyers
Step-by-step explanation:
The Volunteer Club has 78 people that are marching in a parade and each person is supposed to give out out 55 flyers about volunteering. To know the number of flyers that will be needed, we multiply the number of people by the number of flyers each person is holding. This will be :
Total number of flyers needed:
= 78 × 55.
= 4290
There will be 4290 flyers needed.
Answer:
The sale price is $37.02.
Step-by-step explanation:
With the information provided, you can find the sale price by calculating 33% of the price which is the discount and subtracting that amount from the price:
$55.25*33%=$18.23
$55.25-$18.23=$37.02
According to this, the answer is that the sale price is $37.02.
For this case, we have the following equation:
![p = 2 (l + w) ](https://tex.z-dn.net/?f=p%20%3D%202%20%28l%20%2B%20w%29%0A)
Where,
l: length of the rectangle
w: width of the rectangle
We can rewrite the equation to find the perimeter of the rectangle.
For this, we can apply the distributive property.
We have then:
