You are mailing a package that weighs 8 pounds, and sending it first class. the post office charges $0.44 for the first ounce, and charges $0.20 for each additional ounce. how much is the total cost to mail this package?

Total cost to mail this package is $25.84.

Step-by-step explanation:

You are mailing a package that weighs = 8 pounds

The post office charges for the first ounce = $0.44

and for each additional ounce  = $0.20

1 pound = 16 ounces

8 pound = 128 ounces

Charge for 1 ounce 0.44 and additional ounces are = 128-1 = 127 ounces

Total cost to mail this package = 0.44 + ( 127×0.20) = 0.44 + 25.40 = $25.84

Total cost to mail this package is $25.84.

1 pound -= 16 ounces

8*16 = 128 total ounces

128-1 = 127

127*0.20 = 25.40 = 0.44 = $25.84

210 meters

Step-by-step explanation:

x² + 32500 = 76600

x² = 76600 - 32500

x² = 44100

This already is a perfect square

x = 210

(x is a side, so can't be negative. Therefore only positive square root)
