This year, 72 students completed projects for the science fair. This was 23 more students than last year. How many students completed projects for the science fair last year?

Respuesta :

fairytinker92

Answer:

Last year: 49 students

Step-by-step explanation:

There were 23 more students this year than last year. This means that 72 is equivalent to x, or a random number, plus 23

If 23 + x =72

Then x = 72 - 23

Which means that x = 49, or that the number of students that completed projects for the science fair is 49.

Hope this helps!!!
