Answer:

1 pound

Step-by-step explanation:

Given the cost function of two domestic courier services.

We want to determine the weight (x) at which the costs (y) will be the same.

Since y=4x+1 and y=3x+2, then:

4x+1=3x+2

4x-3x=2-1

x=1 pound

When the weight of the parcel is 1 pound, the total cost of the parcel will be the same for the two domestic courier.
