Answer:
The total budget of last year is $50,000 .
Explanation:
Given as :
The percentage of budget spend on entertainment = 9%
The total budget of this year = $3000 more than that of last year
The money that will be spend this year on entertainment = $4770
Let The total budget of last year = $A
Let The total budget of this year = $B
Now, According to question
Percentage of budget spend on entertainment × total budget of this year = money that will be spend this year on entertainment
Or, 9 % × $B = $4770
Or,
× B = 4770
∴ B =

i.e B = $53,000
So,The total budget of this year = B = $53,000
Again
∵ The total budget of this year = $3000 more than that of last year
i.e The total budget of this year = $3000 + total budget of last year
Or, B = $3000 + A
Or, A = B - $3000
Or, A = $53,000 - $3,000
∴ A = $50,000
So,The total budget of last year = A = $50,000
Hence, The total budget of last year is $50,000 . Answer
