Step-by-step explanation:

'The local Walmart sold 67 televisions on Tuesday, 79 televisions on Wednesday, 195 televisions on Saturday, and 82 televisions on Sunday. How many televisions were sold in all over the weekend?"  Figuring the answer to this problem involves adding up the #s of TVs sold on the weekend only.  In other words, we add together the 195 TVs sold on Sat. and the 82 sold on Sun., obtaining 277.  This is the answer to your first question:  The number of TVs sold in all over the weekend was 277.

"The parking rates at the hospital’s parking garage are 50 cents for the first hour and 25 cents for each additional hour. If Juan parks in the hospital’s parking garage for 8 hours, how much will the total charge for parking be?"

Juan will pay $0.50 for the first hour.  This leaves 7 hours.  He will pay $0.25 for each additional hour, that is, he will pay 7 times $0.25 for the last 7 hours of parking.  This comes to $0.50 + 7($0.25) = $2.25 total.

"Tom is on a diet. His diet plan allows him to have 1,000 calories for dinner. He’s chosen a menu of enchiladas (537 calories), asparagus (96 calories), orange salad (78 calories), and cake (633 calories). If he eats this meal, will Tom be staying on his diet?"  Add together the 537, 96, 78 and 633 calories contributed by the enchiladas, asparagus, orange salad and cake.  Does this sum amount to more or less than 1000 calories?  No.  The total is 1344 calories, 344 more than he is allowed.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
