4P
M = 769 + 4P (1st equation)
1300 - 1M - 4P = 51 (2nd equation)
P = ?
1st into 2nd
1300 - 1(769 + 4P) - 4P = 51
1300 - 769 - 4P - 4P = 51
531 - 8P = 51
531 - 51 = 8P
480 = 8P
480/8 = P
P = 60
4P
M = 769 + 4P (1st equation)
1300 - 1M - 4P = 51 (2nd equation)
P = ?
1st into 2nd
1300 - 1(769 + 4P) - 4P = 51
1300 - 769 - 4P - 4P = 51
531 - 8P = 51
531 - 51 = 8P
480 = 8P
480/8 = P
P = 60
Total Cost = 1300 - 51 = 1249
This total cost is for M + 4P.
Since M = 4P + 769,
(4P + 749) + 4P = 1249
8P = 480
P = 60
Cost of a pillow is 60.
This total cost is for M + 4P.
Since M = 4P + 769,
(4P + 749) + 4P = 1249
8P = 480
P = 60
Cost of a pillow is 60.
