The simplified expression to find the 8 % markup on the robotic toy would be 1.08 r .
How to simplify the expression ?
The expression r + 0. 08 r represents the cost of a new robotic toy after an 8 % markup .
To simplify this expression, you can factor out the common factor of r from both terms.
Factoring out r means that you're essentially taking r as a common factor from both terms:
r + 0. 08r = r ( 1 + 0. 08 )
Now, you can perform the addition inside the parentheses:
1 + 0. 08 = 1. 08
So, the simplified expression is:
r (1.08)
1.08 r
The full question is:
The cost of a new robotic toy after an 8% markup can be represented by the expression r + 0.08r. Simplify the expression.
