Question

Please explain how i'm supposed to do this question :)
The table below shows the cost of mailing packages that weigh different amounts.

If the cost continues to increase as shown in the table, how much will it cost to mail a package that weighs exactly 11 ounces?
F) 2.87
G) 4.87
H) 3.04
J) 5.87
Again not asking for you to give me the direct answer, just need to know how to do solve this question :)

Answer 1

So can you see a pattern in how the cost increases? Can you continue on that pattern? For example, can you guess the cost for 5.01 to 6 ounces?

Answer 2

if you notice, the cost increases by $0.17 for each ounce increase in weight!
