Let's denote the amount the school spent last year as "x". According to the given information, the school plans to spend twice the amount it did last year, which can be represented as "2x". However, since they already have the disco ball from last year and it cost $150, we need to subtract this amount from the total budget of $1,500. This can be represented as "2x - 150 = 1500".
