Question

David wants to place an order of supplies. His budget is 8 percent higher than it was last month. If his budget last month was $352.86, what is his budget for this month?

Answer 1

Well, this month he has 8% more than last, so that means, if 352.86 is 100%, then this month he has 100%+8% or 108% of that

now, how much is 108% of 352.86?

well    $\bf \begin{array}{ccllll} amount&\%\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 352.86&100\\ x&108 \end{array}\implies \cfrac{352.86}{x}=\cfrac{100}{108}$

solve for "x"

Answer 2

Answer:

His budget for this month is $381.09

Step-by-step explanation:

We can solve this question using a simple rule of three.

His budget last month, of $352.86, was 100% = 1. His budgets this month, which is x, is 8% higher, so 100+8 = 108% = 1.08. So

$352.86 - 1

$x - 1.08

$x = 1.08*352.86$

$x = 381.09$

His budget for this month is $381.09
