Luisa found great deals on the target dollar spot. She bought 35 items and spent a total of 100 dollars on earbuds (2 dollars each) and fuzzysocks (3 dollars each). How many earbuds did she buy? how many fuzzy socks did she buy?

$2 *  earbuds  bought  +  $3 * fuzzy socks bought =  100

 

2x  +  3 ( 35  - x)  =   100

 

2x  +  105  - 3x   =100

 

-x  =  100  -  105

 

-x  = -5

 

x = 5   =number of earbuds bought

 

35  -5  =   30   =  fuzzy socks bought
