## Algebra 1: Common Core (15th Edition)

You have to set their totals to $34.60$.Tyson's yarn is $6.25$ and he needs 2 knitting needles. Jillian's yard will be $3(6.25)=18.75$ and she needs one knitting needle. Thus: $34.60=18.75 +x+6.25+2x$ (simplify like terms) $34.60=25+3x$ (subtract 25 from both sides) $9.60=3x$ (divide both sides by 3 to isolate the variable) $3.20=x$ The cost of each knitting needle is $3.20$.
