If 3 times a certain number is increased by 4 the result is 28. if x is "the number," which of the following equations could be used to solve for the number?

That's the answer to the question

20(5) + 5(20) + 95.50 = money in account100 + 100 + 95.50 = $295.5Part B = $295.5If Marla's mom deposited $10 after each car wash the coefficient would change.20c+5w+95.50 - the 20 beside the c is the coefficient and the 95.50 is the constant. A coefficient is the number being multiplied to the variable. In this case c is the variable and 20 is the coefficient. Therefore the constant would change.Part C = If Marla's mom deposited $10 after each car wash the coefficient would change.
