Please see below solution:
Let x = number of books that Bryan reads2x for amanda = Amanda 3x - 4 for Colin Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)
[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month.
And Colin 11 books a month. 3(5) - 4 = 11
Part A
c - number of washed cars
Answer: 400 + 5c > 900
Part B
400 + 5c > 900 | - 400
400 + 5c - 400 > 900 - 400
5c > 500 | : 5
5c : 5 > 500 : 5
c > 100
Answer: 100 cars
