Answer:
536 posters
Step-by-step explanation:
So the club only has $1500 to spend, you can write this down as the beginning of your equation (1500=)
Now we know that the printer charges 160 as a BASE so you should now have (1500=160)
We also know that it costs an extra $2.50 per poster. You can rewrite this as:
1500=160+2.5(x)
Now subtract 160 from both sides to get:
1340=2.5(x)
Now divide 2.5 from both sides to get x by itself:
536=x
Therefore they are able to afford 536 posters
