Respuesta :

it went up from 15.50 to 18.60, so it really went up 3.10.

if we take 15.50 to be the 100%, what is 3.10 off of it in percentage?

[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 15.50&100\\ 3.10&p \end{array}\implies \cfrac{15.50}{3.10}=\cfrac{100}{p}\implies p=\cfrac{3.10\cdot 100}{15.50}[/tex]

Answer:

20%

Step-by-step explanation:

rate of increase = (change in value/ original value) * 100

  1. we first find the change in price = new price - old price = 18.60 - 15.50 = 3.10.
  2. Next we'll divide the above value, by the original value = 3.10/15.50 = 0.2.
  3. lastly we multiply 0.2 with 100 = 20%

So Bruce's new wage increased by 20%

I hope it helps
