Mathematics is not my strong suit for this one. I would appreciate your solutions to this answer. Plane A was 26,000 feet in the air and descending at a rate of 2800 feet per minute. Plane B took off from the ground ascending at 2400 feet per minute. Write an equation to represent the height (y) of each plane in terms of the number of minutes (x). At how many minutes will the planes be the same height, and what is that height?

An office supply company conducted a survey before marketing a new paper shredder designed for home use. in the survey, 80 % of the people who tried the shredder were satisfied with it. because of this high satisfaction rate, the company decided to market the new shredder. assume that 80 % of all people are satisfied with this shredder. during a certain month, 100 customers bought this shredder. find the probability that of these 100 customers, the number who are satisfied is 69 or fewer.
