Let x be the cost of 1 pound of jelly beans
Let y be the cost of 1 pound of gummy worms
Diana bought 5 pounds of jelly beans and 3 pounds of gummy worms for $58:
[tex]5x+3y=58[/tex]Monica bought 6 pounds of jelly beans and 3 pounds of gummy worms for $66:
[tex]6x+3y=66[/tex]Solve by elimination method:
1. Subtract the equations:
2. Solve x:
[tex]\begin{gathered} -x=-8 \\ x=8 \end{gathered}[/tex]3. Use the value of x to find y:
[tex]\begin{gathered} 5x+3y=58 \\ 5(8)+3y=58 \\ 40+3y=58 \\ 3y=58-40 \\ 3y=18 \\ y=\frac{18}{3} \\ y=6 \end{gathered}[/tex]Solution: x=8 y =6
Then, A pound of jelly beans costs $8.00 and a pound of gummy worms costs $6.00
