Ivan and Jennifer went to the local deli to pick up sandwiches for the girls and boys soccer teams. Ivan ordered 10 roast beef subs and 8 Italian subs for a total of $89. Jennifer ordered 6 roast beef subs and 5 Italian subs for a total of $54.35. One way to represent this situation is given in the system of equations below, where r represents the price of a roast beef sub, and i represents the price of an Italian sub.

10r+8i=89.00

6r+5i=54.35

Use the elimination method to figure out the price of each sandwich.

roast beef sub $5.50; Italian sub $4.25
roast beef sub $5.50; Italian sub $4.25

roast beef sub $5.45; Italian sub $4.30
roast beef sub $5.45; Italian sub $4.30

roast beef sub $5.10; Italian sub $4.75
roast beef sub $5.10; Italian sub $4.75

roast beef sub $5.00; Italian sub $4.85
