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.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C"
Given,
Stacy has s stamps.
Then, from the question it is clear that Dominic has 3s-6 stamps
So, the number of stamps that Mary received will be 3s-6 +s = 4s-6
Hence, option C is the correct option.
