It had a 150% increase in price

100* 1.5 = 150
150+100 = 250

Well, if we take $100 to be the 100%, and then it went up by $150, how much is $150 off of it in percentage?

$\bf \begin{array}{ccll}
\$&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
100&100\\
150&x
\end{array}\implies \cfrac{100}{150}=\cfrac{100}{x}\implies x=\cfrac{150\cdot 100}{100}$

The vertex of the parabola below is at the point (-4,-2) wich of the equations below could be the one for this parabola

MrRissso [65]

The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation $y(x)=a(x+4)^2-2$ where $a$ is any real number with the exception that $a\neq 0$ .

The reason any equation of the form $y(x)=a(x+4)^2-2$ works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola $y=x^2$ . The different variations are archived by varying the constant $a$ . When $a$ is negative, the parabolas will face downwards. When $a$ is negative, the parabolas will be face downwards.

If you have a budget of 12% of your monthly income for groceries how much can you spend on groceries if you earn 950 by weekly

Fofino [41]

If you earn 950 biweekly and we assume a month is 4 weeks, then your monthly income is 950 * 2 or 1900, now how much is 12% of 1900?

bear in mind that whatever% of anything is just (whatever/100) * anything.

thus, 12% of 1900 is just (12/100) * 1900.
