Answer:
I think it is 10
Step-by-step explanation:
Only because I believe n is still unknown and 4 must be multiplied
example
4(10 + n)
40 + 4n
now if P = 10
4(n + p)
4(n + 10)
4n + 40
Answer:
8 hours
Step-by-step explanation:
If two people shovel at the same rate, they can do the job in half the time.
We have ...
(Dad) + (Mom + Isabel) ⇒ 2 hours . . . . half as long as Dad alone
Dad ⇒ 4 hours
This tells us that ...
(Mom +Isabel) = 4 hours
We know that ...
Isabel ⇒ 2×4 hours = 8 hours . . . . twice as long as Mom + Isabel
So, we conclude ...
Mom ⇒ 8 hours
It would take Mom 8 hours to shovel the driveway herself.

<em>Additional comment</em>
The rates add when expressed as driveways per hour.
total = Dad + Mom + Isabel
1/2 = 1/4 + 1/m + 1/(2·4)
1/m = 4/8 -3/8 = 1/8
m = 8 . . . . . it takes Mom 8 hours by herself.
