Answer:
6 days
Step-by-step explanation:
Step one:
Given data
For Ray
He has 16 pages already
Now he is writing 2 pages per day
let x be the number of days
and y be the total number of pages writen
the linear function for the situation is given as
y=2x+16-------------1
For Claudia
He has 2 pages already
Now he is writing 4 pages per day
let x be the number of days
and y be the total number of pages writen
the linear function for the situation is given as
y=4x+2-------------2
Step two:
let us equate equation 1 and 2 to find x
2x+16=4x+2
collect like terms
2x-4x=2-16
-2x=-12
divide both sides by -2
x=12/2
x=6
Therefore it will take 6 days for them to have the same number of pages
The answer should be the first one, SF = 1/2
