This year, the advertising budget of the park committee is 12% more than it was last year. If the advertising budget is $300 more this year, how many dollars was the budget last year?
PLEASE HELP I DO NOT KNOW WHAT TO DO!!!
12% of budget=300
1% of budget = 300/12 = 25
so 100% of budget = 25*100
=2500
A few key terms in your math problem:
"is" means "equals"
"of" means multiply.
% is "per 100" (Think of 1 cent being 1/100 of a dollar)
So, from there, translate your equation. We know that $300 is 12% of last year's budget. So:
300 = (is) 12/100 (12 per-cent) x (of) LastYear'sBudget
We'll call last year's budget "x"
300=.12x
300/.12 = x
x=2500
Just knowing what the terms mean makes a huge difference to know how to translate the problem into an equation. Learn those ideas and the rest will come more easily :)

To find out the budget of last year, you can follow these steps:
Step 1: Set up the equation
Let's assume the budget of last year as "x" dollars. According to the information given, the budget of this year is 12% more than last year's budget and $300 more in total. So we can write the equation as:
x + 12% of x = x + $300
Step 2: Convert the percentage to decimal form
To calculate the 12% increase in the budget, we need to convert the percentage to decimal form. Divide 12 by 100:
12% / 100 = 0.12
Step 3: Solve the equation
Now substitute the decimal form of 12% into the equation:
x + 0.12x = x + $300
Simplify the equation:
1.12x = x + $300
Subtract "x" from both sides of the equation:
1.12x - x = $300
0.12x = $300
Step 4: Solve for x
Divide both sides of the equation by 0.12:
x = $300 / 0.12
x = $2,500
Therefore, the budget of last year was $2,500.
