Answer:
length of each plan A work out: 1 hour
length of plan B work out:
hours
Step-by-step explanation:
Let x represents the time taken to do plan A
y represents the time taken to do plan B
On Monday there were 5 clients who did Plan A and 2 who did Plan B.
Miguel trained his Monday clients for a total of 6 hours
5x + 2y = 6 -----------> equation 1
On Tuesday there were 3 clients who did Plan A and 8 who did Plan B. .He trained his Tuesday clients for a total of 7 hours
3x + 8y = 7 -------------------> equation 2
Now we solve for x and y
Let multiply the first equation by -4 to eliminate y
-20x -8y = -24
3x + 8y = 7
------------------------ (add both equations)
-17x = -17
Divide both sides by -17
So x= 1
Plug in 1 for x in first equation and solve for y
5x + 2y = 6
5(1) + 2y = 6
5 + 2y =6
Subtract 5 on both sides
2y = 1
y = 1/2
length of each plan A work out: 1 hour
length of plan B work out:
hours
