Determine if the rates $168 raise for 24 cars and $280 for washing 40 cars are equivalent

3x + 4y -25 =0 represents the amount of change sianna should recieve

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
