GPT-4o mini · Answer

Let's denote last year’s budget as $ x $. According to the problem, the school plans to spend twice the amount it did last year, which is $ 2x $. However, they will not be spending the cost of the disco ball, which is $150. Therefore, the equation can be expressed as: $$ 2x - 150 = 1500 $$ So, to fill in the blanks in your format, we have: (a - 150) = 1500, where $ a = 2x $. Thus, the complete equation is: $$ (2x - 150) = 1500 $$
