Question

Ally got a raise in her monthly pay, from $15.90 to $17.95 . What is the increase percent ?

Answer 1

The percentage increase in Ally monthly pay is 12.89 %

Explanation:

Given as :

The initial pay of Ally = i = $ 15.90

The final pay of Ally = f = $ 17.95

Let The increase percentage = x %

Now, Percentage increase % =
`(\textrm Final pay - \textrm initail pay)/(\textrm initial pay)` × 100

Or, x =
`(\textrm f - \textrm i)/(\textrm i)` × 100

Or, x =
× 100

Or, x =
`(2.05)/(15.90)` × 100

∴ x = 0.1289 × 100

I.e x = 12.89

So, increase percentage = x = 12.89

Hence The percentage increase in Ally monthly pay is 12.89 % Answer
