Sandra is 4 feet tall. pablo is 10% taller than sandra, and michaela is 8% taller than pablo.

explain how to find michaela's height with the given information

Height of Sandra that is already mentioned in the question is = 4 feet
Percentage by which Pablo is taller than Sandra = 10%
Height by which Pablo is greater than Sandra = (10/100) * 4
                                                                         = (4/10)
                                                                         = 0.4 feet
Then height of Pablo is = 4 + 0.4
                                     = 4.4 feet
Now we can find the height of Michaela as she is 8% taller than Pablo.
Percent by which Michaela is taller than Pablo = 8%
Height by which Michaela is greater than Pablo = (8/100) * 4.4
                                                                            = (2 * 4.4)/25
                                                                            = 0.35 feet
Then the height of Michaela = (4.4 + 0.35) feet
                                             = 4.75 feet
So height of Michaela is 4.75 feet. This is the way this problem has to be solved.

If you would like to know how tall is Michaela, you can calculate this using the following steps:

Sandra ... s = 4 feet tall
Pablo ... p = 10% taller than Sandra: 110% * s = 110% * 4 = 110/100 * 4 = 4.4 feet tall
Michaela ... m = 8% taller than Pablo: 108% * p = 108% * 4.4 = 108/100 * 4.4 = 4.752 feet tall

Result: Michaela is 4.752 feet tall.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
