8($2.59)+5($5.59)−2x=$49.57
8 times open paren 2 point 5 9 dollars close paren plus 5 times open paren 5 point 5 9 dollars close paren minus 2 x is equal to 49 point 5 7 dollars
8($2.59)+5($5.59)+2x=$49.57
8 times open paren 2 point 5 9 dollars close paren plus 5 times open paren 5 point 5 9 dollars close paren plus 2 x is equal to 49 point 5 7 dollars
2x−8($2.59)+5($5.59)=$49.57
2 over x minus 8 times open paren 2 point 5 9 dollars close paren plus 5 times open paren 5 point 5 9 dollars close paren is equal to 49 point 5 7 dollars
x2+8($2.59)+5($5.59)=$49.57
x over 2 plus 8 times open paren 2 point 5 9 dollars close paren plus 5 times open paren 5 point 5 9 dollars close paren is equal to 49 point 5 7 dollars
Lilly's cost is $25.68
and Samuel's cost is $24.09
Lilly's cost is 25 point 6 8 dollars and Samuel's cost is 24 point 0 9 dollars
Lilly's cost is $24.58
and Samuel's cost is $24.99
Lilly's cost is 24 point 5 8 dollars and Samuel's cost is 24 point 9 9 dollars
Lilly's cost is $25.93
and Samuel's cost is $26.34
Lilly's cost is 25 point 9 3 dollars and Samuel's cost is 26 point 3 4 dollars
The correct equation is 8($2.59)+5($5.59)+2x=$49.57.
Based on their supplies, Lilly should pay $25.93 and Samuel should pay $26.34.
