An express mail company charges $8 for a package weighing 1 pound or less. Each additional pound or part of a pound costs $2 more.
What is the cost to send a package weighing 7.4 pounds

5 pounds

Step-by-step explanation:

$24

Step-by-step explanation:

y = total cost  x=each addition pound or part of a pound

y = 8 + 2x

Substitute the value of x in. (8 because it is still 2 dollars more for the 0.4)

y = 8 + 2(8)

Solve

Total cost = $24
