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 .(2 points)

Question

__(a - __) = __

Answer 1

To determine last year's budget, we can set up the equation based on the information provided. Let's denote last year's budget as \( x \).

According to the problem, this year the school plans to spend twice last year's budget, minus the cost of the disco ball, which was $150. Therefore, the equation can be set up as follows:

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

To fill in the blanks in your format:

(a - __) = __

We can express it as:

(2x - 150) = 1500

So, the filled blanks would be:

• (a - 150) = 1500

Where \( a \) represents \( 2x \). Thus, if we take \( a = 2x \), the equation reads as follows:

(2x - 150) = 1500

Thus, the answer is:

(a - 150) = 1500
