A school plans to spend twice the amount it did last year on its winter dance, less the cost of the disco ball which was $150, since they have it from last year. A total of $1,500 is being spent this year. Fill in the blanks to write an equation that will determine the amount of last year’s budget, a

blank(a −blank) =blank

1 answer

Let \( x \) represent last year’s budget amount.

According to the information provided, the school plans to spend twice last year's amount, minus the cost of the disco ball. Therefore, we can express the equation as follows:

\[ 2x - 150 = 1500 \]

Now, filling in the blanks, we get:

  • a = 2
  • blank = x
  • blank = 150
  • blank = 1500

So the complete equation is:

\[ 2(x - 150) = 1500 \]
