The package weighs 30 ounces.
Step-by-step explanation:
Mailbox Plus charges;
Charges per ounce = $0.25
Let,
x be the number of ounces.
M(x)=5+0.25x
United packges charges;
Charges per ounce = $0.35
U(x) = 2+0.35x
Cost will be same when the functions are equal;
M(x) = U(x)
Dividing both sides by 0.10
The package weighs 30 ounces.

The answer is 7/20. First, you subtract 2 1/4 and 1 2/5. You have to make a common denominator. The common denominator is 20. Now you have 2 5/20 - 1 8/20. You can't subtract 5 from 8 so you have to regroup. Now you have 1 25/20 - 1 8/20. You get 7/20
The minimum number of bags of seed the contractor needs to buy the to cover the entire lawn is 4
<h3>How to determine the number of bags</h3>
Start by calculating the area of the entire field using:
--- area of square
So, we have:
Next calculate the area of the porch using:
-- area of trapezium
So, we have:
The difference between the areas of the entire field and porch is the area of the lawn.
So, we have:
The above means that, the area of the lawn is 1940 square yards
If one bag of grass covers 600 square yards, then the number of bags that can cover 1940 square yards is:
Round to the next highest integer
Hence, the minimum number of bags of seed is 4 bags
