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

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
