The remainder of available funds after buying food is 7/24 of \$1200 or \$350. After spending 5/7 of that (\$250) for clothing and other expenses, \$100 is left. This could also be computed from the formula X = 1200(1 - 17/24)(1 - 5/7) =1200(7/24)(2/7) = 1200*(1/12)

1. 1.25P = 1200. P = 1200 / 1.25 = \$960 2. 960-960r = 1200-1200r - 175.20. 960-960r = -1200r + 1024.80. -960r + 1200r = 1024.80 - 960. 240r = 64.8. r = 64.8 / 240 = o.27 = 27%.

Alg 1
w^2 + 75w - 1200 = 0 I could not find the answer. It needs to be factors of 1200. Since the third term is negative, one needs to be negative and the other positive to add to 75. For example, 100 and -12, but that sums to 88. I could use 80 and -15, but that gives me 65. Do you...

Math
the two planes cover 580+620=1200 miles per hour. So, they travel for 2700/1200 = 2.25 hrs before meeting. (why?) In that time, the 2nd plane has traveled 2.25*620 = 1395 miles, so it is 1305 miles from LA.

Revenue - Cost = 1200 Let N be the number produced (and sold) The revenue is 6N. The cost is 900 + 1.5 N. 1200 = 6 N - (900 + 1.5N) = 4.5 N -900 4.5 N = 2100 N = 467 N has to be an integer, so you round to the next higher integer. N=466 would result in a loss.
