3×(2+6)+4×5 is/= 44,

3×2+3×6+4×5=44

5×4+3×(6+2)=44

(6+2)×3+4×5=44

3×2+(6+4)×5= 56

So your answers are A, B, and C.

Y is directly proportional to x.
Brums [2.3K]
If y is directly proportional to x then y:x.
When y = 30, x = 6 then 30/6 = 5:1. Therefor for every 1x there is 5y vice versa. When x = 12, then y = 5 * 12 = 60.
Therefore y = 60 hence 60:12

a television normally sells for $499 what is now discounted 25%. The sales tax rate is 6.5%. What is the total cost of televisio
matrenka [14]
Hmmm what is now discounted?  well, let's assume it sells normally for 499 and is discounted today at 25%, how much is that?

well, if we take 499 to be the 100, how much is 25%?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
499&100\\
d&25
\end{array}\implies \cfrac{499}{d}=\cfrac{100}{25} \cfrac{499\cdot 25}{100}=d
\\\\\\
124.75=d\qquad \textit{so the new price is }499-124.75\implies 374.25

now, applying the sales tax to the discounted price.

if we take 374.25 to be the 100%, how much is 6.5%?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
374.25&100\\ t&6.5
\end{array}\implies \cfrac{374.25}{t}=\cfrac{100}{6.5}\implies \cfrac{374.25\cdot 6.5}{100}=t

so, the total cost will then be 374.25 + t.
