0.75x > = 250

x > = 250/0.75

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

Kaylie Gates · Answer 2

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.
