Step-by-step explanation:
For part A:it has to be equal because if x=3 and they’re talking about 4x, that 4*3=12 and 12-1=11
For part B:it is 7 because if c=7 and it is 8x, 8*7=56 and 56+1=57
For Question 2/part a: if each ticket costs the same, you could call the price of the ticket x. The equation can be x*25=$870.75 which means that you have to divide870.75 by 25 which would equal $34.83 and you could plug $34.83 in x and solve the equation
For question 3: you could say:3 is not equal to 3+10 or 5 is not equal to 5+10
For question 4: I don’t know if this is right but I think that that price is dependent on the time because you won’t get the money if you don’t spend any time doing your job
Hope it helps!
