Question

Dominic and Stacy each have a stamp collection. Dominic has six fewer stamps than three times the number of stamps Stacy has. Dominic and Stacy decide to give all of their stamps to their younger sister, Mary. If Stacy had s stamps, which expression represents the number of stamps that Mary received?

(3s - 18)(3s - 6)

2s - 18

4s - 6

4s - 18

Answer 1

I'm pretty sure it's the first option.

Since Stacy has 3 times more stamps than Dominic does, you write 3s - 6
If you multiply 6 x 3 you get 18, giving you 3s - 18

Answer 2

The number of stamps that Mary received are 4s-6

What is linear equation ?

"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.
