Answer:
[tex]Expression = x + 18x\%[/tex]
[tex]Expression = 1.18x[/tex]
Step-by-step explanation:
Given
Represent their goal with x
Additional = 18%
Required
Write two expressions to describe the total percentage
The expression is derived using:
[tex]Expression = Goal + Additional[/tex]
This gives:
[tex]Expression = x + 18\% * x[/tex]
[tex]Expression = x + 18x\%[/tex]
Solving further (Express percentage as decimal)
[tex]Expression = x + 0.18x[/tex]
[tex]Expression = 1.18x[/tex]
