0.75x > = 250
x > = 250/0.75
x > = 333.33....so they would have to sell at least 334 of them

Ok so lets say that the number of lanyards is equal to b. We have to write an equation that solves for b. That would be:

0.75b ≥ 250

Now you solve the equation

0.75b ≥ 250
——— —— (divide both sides by 0.75)
0.75 0.75

b ≥ 333.3

You have to round that up because you can’t sell part of a lanyard. So the answer is:

The seniors have to sell at least 334 lanyards.
