Data
• Promotion: 2%
,• Monthly salary: $2601
Procedure
The original salary is 100% of the quantity, as the raise ($2601) is 102%. To solve this problem we have to build a relation between these quantities:
[tex]\frac{x}{100\%}=\frac{2601}{102\%}[/tex]where x represents the quantity he was making before.
Multiplying both sides of the equation times 100%:
[tex]100\%\times\frac{x}{100\operatorname{\%}}=\frac{2,601}{102\operatorname{\%}}\times100\%[/tex][tex]x=\frac{2,601}{102\operatorname{\%}}\times100\%[/tex]Simplifying:
[tex]x=\frac{260,100}{102\operatorname{\%}}[/tex][tex]x=\frac{260,100}{102\operatorname{\%}}=2550.0[/tex]Answer: $2250.0
