Answer:
Step-by-step explanation:
She has the option for supplying the total of 106 items. This 106 items can be either tacos or burritos or both with a total of 106 items.
If 79 tacos are sold, then it gives [tex]79 \times 3.50 = 276.5[/tex]
She needs to make $470 in total.
She needs to make $(470 - 276.5) = $193.5 more till now.
After selling 79 tacos, she has an option to sell maximum (106 - 79) = 27 burritos.
If she wants to make $193.5, she needs to sell [tex]\frac{193.5}{6.5} = 29.7[/tex] that is 30 burritos.
As she can sell 27 burritos in maximum, so there is no possible solutions.
