julian want to buy a new ipod that costs $220. he goes into a store and sees that it is on sale and has a 35% discount. he will

tigry1 [53]

Answer:

The final cost for him is;

$\text{ \$154.44}$

Explanation:

Given that the ipod costs $220;

$C=\text{ \$220}$

The store gives a 35% discount, which means he will only pay 65% of the original cost;

$100\text{\%- 35\% = 65\%}$

The store price is;

$\begin{gathered} P=\text{ 65\% of \$220} \\ P=\frac{65}{100}\times\text{ \$220} \\ P=\text{ \$143} \end{gathered}$

Also he will need to pay additional 8% sales tax on the discounted price P;

$\begin{gathered} t=8\text{\% of P} \\ t=8\text{\% of \$143} \\ t=\frac{8}{100}\times\text{ \$143} \\ t=\text{ \$11.44} \end{gathered}$

The final cost he need to pay is the sum of the discounted price and the sales tax;

$\begin{gathered} F=P+t \\ F=\text{ \$143 + \$11.44} \\ F=\text{ \$154.44} \end{gathered}$

Therefore, the final cost for him is;

$\text{ \$154.44}$

$d = 4n -2 \\d + 2 = 4n\\\frac{1}{4}d + \frac{2}{4} = n\\\\n = 0.25d + 0.5$

For a 3-penny nail
$n = 0.25d + 0.5\\ n = 0.25(3) + 0.5\\n = 0.75 +0.5\\\\n = 1.25$

For a 6-penny nail
$n = 0.25d + 0.5\\n = 0.25(6) + 0.5\\n = 1.5 + 0.5\\\\n = 2$

For a 10-penny nail
$n = 0.25d + 0.5\\n = 0.25(10) + 0.5\\n = 2.5 + 0.5\\\\n = 3$

Hope that helped :)

To get the answer we have to substitute x=3 and add 6 to the result.
Lets do this
f(x)=7-2x
f(3)=7-2*3=7-6=1
f(3)+6=1+6=7 - its the result

Ella and her children went into a bakery and where they sell cookies for $0.50 each and brownies for $2.25 each. Ella has $15 to

matrenka [14]

Answer: 5 brownies

Step-by-step explanation:

cookies = 5 x $0.50 = $2.5

$15 - $2.5 = $12.5

$12.5 divided by $2.25 = $5.555

so at the most ella can buy 5 brownies if she buys 5 cookies
