To determine how many packages need to be sent for the second service to cost less than the first service, we can set up the inequality.

Let x represent the number of packages.

Define the cost for each service:

First Service

Charges a $9 fee for the first package and $5 per additional package.

Cost for x packages: 9 + 5(x - 1) = 9 + 5x - 5 = 4 + 5x

Second Service

Charges a $15 fee for the first package and $3 per additional package.

Cost for x packages: 15 + 3(x - 1) = 15 + 3x - 3 = 12 + 3x

Set up the inequality to find when the second service is cheaper than the first se...
