340 - 40 = 3 times the cost
300 = 3 times the cost
100=cost

if cost = x
SP = 340 = 40 + 3x
3x = 300
x= 300/3=100
i.e. Cost is $100

$100.
First,you take away the $40. That leaves you with $300,right? $300 is three -times- the cost. Therefore,to find the cost,divide 3 into $300. $300 divided by 3 is $100.
Good luck with algebra 1. =)
