Question

Tricia got 6% raise on her weekly salary. The raise was $42 per week. What was her original weekly salary in dollars per week

Answer 1

Step 1

Write an expression that can help find the original salary

`(106)/(100)* x=x+42`

Step 2

Simplify the equation

`\begin{gathered} 1.06x=x+42 \\ 1.06x-x=42 \\ 0.06x=42 \\ (0.06x)/(0.06)=(42)/(0.06) \end{gathered}`
`x=\text{\$700}`

Hence, Tricia's Original weekly salary in dollars per week=$700
