A school plans to twice the amount 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.

Question

_ ( a - _ ) = _

Answer 1

To formulate the equation, we need to break down the information provided:

1. The school plans to spend twice the amount of last year's budget (denoted by \( a \)) minus the cost of the disco ball which was $150.
2. The total amount being spent this year is $1,500.

From this, we can construct the equation: \[ 2a - 150 = 1500 \]

Now we can fill in the blanks:

• The first blank is \( 2a \) (twice the amount of last year).
• The second blank is \( 150 \) (the cost of the disco ball).
• The third blank is \( 1500 \) (the total amount spent this year).

So the complete filled-in equation is: \[ 2a - 150 = 1500 \]
