A coffee shop sells bags of coffee for a regular price of 

$8

 per bag. Kevin bought some bags and used a coupon for 

$10

 off his entire purchase. After applying the coupon, he paid 

$30

. How many bags of coffee did he buy?

Let the entire purchase amount be the number of bags he bought, B,  times the price per bag

 

So   B*8  =  the entire purchase price

 

From  this ...he subtracts  $10     and pays $30

 

So  we have this

 

 

B*8  -  10  =  30       add 10 to both sides

 

B*8  =  40        divide both sides by 8

 

B  = 5  bags

 

 

cool cool cool
