Step-by-step explanation: Given in the question that Lana completed a 10-mile race in 90 minutes by running and walking both. She usually runs at a pace of 8.5 minutes per mile and walks at a pace of 12 minutes per mile. We need to find the number of minutes for which she ran and walk throughout the race.
Let, Lana runs for 'x' miles and walks for 'y' miles. Then, we have
Multiplying the first equation by 8.5 and subtracting from the second equation, we have
Therefore,
Thus, time for which Lana ran is
And, the time for which Lana walks is
Thus, the answers are

You want at least three food items for each of the 35 guests. That means you want at least 3(35) = 105 bratwursts or hamburgers. You can write this equation:
(number of bratwursts) + (number of hamburgers) (is at least) 105
x + y ≥ 105
Bratwursts cost $1.30 each and hamburgers cost $1.20 each. Your budget is $150. So, you want the cost of the food items to be less than or equal to $150. You can write this equation
(cost of bratwursts) + (cost of hamburgers) ≤ 150
(price of one bratwurst)(number of bratwursts) + (price of one hamburger)(number of hamburgers) ≤ 150
1.3x + 1.2y ≤ 150
