There are 60 tables in a restaurant, with 25% of them seating 2 people. the tables remaining seat 4 people. how many seats are there in the restaurant?

Do 60*0.25 and that's 15. 15 tables seat 2 people. we can also confirm this by doing 15*4 which is 60 (the total amount of tables) since 25%*4=100. then we know the rest of them fit 4 and 60-15=45. Now we do (15*2) + (45*4). {one for the 2 seated tables and the other for the 4 seated ones.} 30+180=210 seats.

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
