Mrs.Hines has 40 ballons for a party.She has 12 more balloons than she had for her last party.How many balloons did she have last party? Is there a different equation you can write to show this problem? Explain

Respuesta :

Answer: 28

Step-by-step explanation:

Let the number of balloons that she had last party be represented by x.

Since Mrs.Hines has 40 ballons for a party which was 12 more balloons than she had for her last party. The number of ballons had last party will be formed into an equation as:

x + 12 = 40

Collect like terms

x = 40 - 12

x = 28

She had 28 balloons last year
