Pierre's hourly rate can lie between $7.5 and $8.25.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Jim earns $41.25 in 5 hours.
Susan earns $30.00 in 4 hours.
So, Jim per hour earning = 41.25 / 5 = $8.25
and, Susan per hour earning = 30/ 4= $7.5
As, Pierre's hourly rate is less than Jim's but more than Susan's.
so, Pierre's hourly rate can lie between $7.5 and $8.25.

Answer:
59
Step-by-step explanation:
5 - 2 • 3 + 6(9 + 1) =
Use the correct order of operations.
Do the addition in the parentheses first.
= 5 - 2 • 3 + 6(10)
Now do the multiplications in the order they appear from left to right.
= 5 - 6 + 60
Now do additions and subtractions in the order they appear from left to right.
= -1 + 60
= 59
