The PTA has 25 members. Each member must pay $5.50 in membership dues. In the first week of school, 11 members paid their dues. The remaining members paid during the second week. How much money was collected in dues during the second week of school?

$77.00

Step-by-step explanation:

25-11= 14

14 x 5.50= 77

Define x and y : let x be the number of laps he run.let y be the number of laps he walk.construct equations :   max completed 10 laps.⇒ x + y = 10max took 25 min to complete the 10 laps.⇒(60+45)x + (3x60)y = 25x60              // convert all minutes into seconds105x +180y = 1500                                // divide by 15 through7x + 12y = 100solve for x and y :   x + y = 10      (1)7x + 12y = 100    (2)from equation 1: x + y = 10x = 10 - ysub x = 10 - y into equation 2 : 7x + 12y = 100  7(10 - y) + 12y = 10070 - 7y + 12y = 1005y = 30y = 6sub y = 6 into equation 1 : x + y = 10x + 6 = 10x = 4find the laps : run = x = 4walk = y = 6  answer: he ran 4 laps.
