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:


(x)/(100\%)=(2601)/(102\%)

where x represents the quantity he was making before.

Multiplying both sides of the equation times 100%:


100\%*\frac{x}{100\operatorname{\%}}=\frac{2,601}{102\operatorname{\%}}*100\%
x=\frac{2,601}{102\operatorname{\%}}*100\%

Simplifying:


x=\frac{260,100}{102\operatorname{\%}}
x=\frac{260,100}{102\operatorname{\%}}=2550.0

Answer: $2250.0
