Answer:
itll take 8 pounds for both DHL and MPS to cost the same
Explanation:
since DHL charges $4 for the first pound and $0.22 for each additional pound, and MPS charges $12 for the first pound and $0.12 for each additional pound, we can write that as 4 + 0.22x = 12 + 0.12x, with the left side representing DHL and the right representing MPS.
If this equation is solved, you will find out that x = 8, which is the number of pounds that DHL and MPS will cost the same at. Therefore, they will charge the same amount for 8 pounds.
